[0001] The present application relates to the technical field of electrical equipment, and in particular to an isolating switch and an electric meter box. Background Art
[0002] An isolating switch is a switching device used to disconnect a circuit with no-load current and isolate the power supply. When in the open state, it can establish a reliable insulation gap to isolate the equipment or line that needs maintenance from the power supply to ensure the safety of maintenance personnel and equipment.
[0003] With the development of smart grids, digitalization and intelligence are placing increasingly higher demands on electrical equipment. Isolating switches, as an important part of terminal power distribution, cannot meet these requirements. Utility Model Content
[0004] The present application provides an isolating switch and an electric meter box, which can facilitate the intelligent and digital use of electricity through the isolating switch.
[0005] In a first aspect, the present application provides an isolating switch, comprising a switch body and a detection module connected to the switch body. The switch body comprises a first housing and functional components within the first housing, the functional components comprising an input terminal, an output terminal, and an isolation contact, the isolation contact being connected between the input terminal and the output terminal. The detection module is connected to the first housing and comprises an output terminal and an output plate, the output plate being connected to a connecting wire electrically connected to the output terminal.
[0006] The input and output terminals are both used to electrically connect to the main circuit, so that the switch body and the detection module are connected in series in the main circuit. The detection module is used to detect the signal parameters of the main circuit, and the switch body is used to control the connection or disconnection of the main circuit through the isolation contact.
[0007] In the embodiment of the present application, the switch body can realize the disconnection or connection of the main circuit, and the detection module can collect signal parameters in the main circuit and complete the detection of the signal parameters so that the user can understand the working status of the main circuit.
[0008] In other words, the isolating switch proposed in this application can take into account both the circuit on-off function and the signal parameter detection function. In this way, it is convenient to manage the equipment in the main circuit according to the working status of the main circuit, and it is convenient to realize the intelligent and digital use of electricity through the isolating switch.
[0009] Optionally, the detection module includes a second housing and a main body, the main body being disposed within the second housing, and the outlet terminals and outlet plate being disposed on the main body. A wire outlet hole is disposed on a side of the second housing facing the first housing, the wire outlet hole penetrating the second housing, and a portion of the connecting wire extends from the second housing through the wire outlet hole and is electrically connected to the outlet terminal.
[0010] In this way, the connecting wire can extend from the second shell near the first shell, which can facilitate the connection between the connecting wire and the outlet terminal and reduce the possibility of the connecting wire being messy or tangled when the distance between the connecting wire and the outlet terminal is large.
[0011] Optionally, the isolating switch also includes a cover body, a first clamping structure is provided on the first shell and / or the second shell, a second clamping structure is provided on the cover body, and the first clamping structure is clamped with the second clamping structure so that the cover body is provided on the outlet end and blocks the connecting wire.
[0012] With the above arrangement, the outlet terminal is covered with a cover, which can reduce the possibility of electric shock caused by exposed connecting wires. In addition, the cover can also protect the connecting wires, preventing them from being pulled and damaged during inspection and maintenance of equipment in the meter box.
[0013] Optionally, the incoming terminal and the outgoing terminal are located on the same side.
[0014] In this way, the incoming line and the outgoing line of the isolating switch are located on the same side. When the isolating switch is connected to the main circuit, the first connecting end and the second connecting end can be connected on the same side, which is convenient for wiring.
[0015] Optionally, the main circuit has a power supply terminal and a load terminal. When the main circuit is connected, current flows in the main circuit from the power supply terminal to the load terminal. At the disconnector, current flows from the input terminal to the output terminal. The detection module is connected to a side of the first housing away from the power supply terminal.
[0016] Through the above arrangement, the switch body can be arranged at the front end of the detection module. In this way, the switch body is arranged between the detection module and the power supply end, and the switch body can play the role of isolation and disconnection.
[0017] Furthermore, the detection module is far away from the power supply end, while the switch body is close to the power supply end. In this way, the relative position relationship between the switch body and the detection module corresponds to the direction of current flow, which can facilitate the connection between the switch body and the detection module and the main circuit.
[0018] Optionally, the detection module further includes a circuit board having a first terminal and a second terminal, the first terminal being connected to a connecting wire, and the second terminal being connected to an external circuit. The main body is electrically connected to the circuit board, and the circuit board is configured to supply power to the main body so that the main body can detect signal parameters of the main circuit. The voltage of the external circuit relative to ground is zero.
[0019] In this way, the first terminal and the second terminal can be connected to the connecting wire and the external circuit respectively. The connecting wire and the external circuit can cooperate to form a loop to provide working voltage for the circuit board, so that the circuit board can power the main body.
[0020] Optionally, the main body includes a terminal structure, a magnetic ring, and a winding. The terminal structure is connected to the second housing. The outlet terminal and the outlet plate are both located on the terminal structure. The winding is wound around the magnetic ring, which is then sleeved around the connecting wire. Both ends of the winding are electrically connected to the circuit board. The winding is used to generate an induction signal based on the current flowing through the connecting wire.
[0021] Because the windings are electrically connected to the circuit board, the circuit board can supply power to the windings, allowing the windings and the magnetic ring body to form a magnetic field. When current flows through the connecting wires, an induction signal is generated at both ends of the windings based on the principle of electromagnetic induction. This induction signal can then be used to calculate the signal parameters of the main circuit.
[0022] Optionally, the detection module is further provided with a communication unit, a controller is connected to the circuit board, and both ends of the winding are electrically connected to the controller. The communication unit is electrically connected to the controller and is in communication with the server, and the controller is used to transmit the signal parameters to the server.
[0023] The setting of the communication unit can connect the controller with the server, so that the control chip can transmit the calculated signal parameters to the server for subsequent processing.
[0024] Optionally, a working device is provided on the circuit board, and the working device cooperates with the main body to detect the signal parameters of the main circuit.

Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
[0049] For example, the embodiment of the present application provides an electric meter box, which includes an electric energy meter and Figure 1 The isolating switch 100 shown in FIG. 1 has an electric energy meter connected to the main circuit and in series with the isolating switch 100. When the main circuit is energized, current flows from the isolating switch 100 to the electric energy meter.
[0050] The energy meter and the isolating switch 100 are arranged in the meter box. On the one hand, the meter box can be used to install and fix the energy meter and the isolating switch 100. On the other hand, the setting of the meter box can also provide protection and isolation insulation for the energy meter and the isolating switch 100, making the use of the energy meter and the isolating switch 100 safer.
[0051] When the main circuit is energized, current flows from the isolating switch 100 to the energy meter. Therefore, the isolating switch 100 is positioned near the positive pole, and the energy meter is positioned near the negative pole. In other words, the isolating switch 100 is positioned in front of the energy meter. This ensures that the isolating switch 100 can isolate and disconnect the current, ensuring safe electricity use.
[0052] The electric energy meter is also provided in the main circuit and is connected in series with the isolating switch 100 . Therefore, the electric energy meter can cooperate with the isolating switch 100 to detect the signal parameters in the main circuit.
[0053] Furthermore, the isolating switch 100 can be used to disconnect and connect the main circuit. When the isolating switch 100 is disconnected, the isolating switch 100 can isolate the power supply so that other equipment in the main circuit can be repaired.
[0054] The isolating switch 100 provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.
[0055] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the present application provides an isolating switch 100, comprising a switch body 10 and a detection module 20 connected to the switch body 10. The switch body 10 comprises a first housing 101 and functional components disposed within the first housing 101. The functional components comprise an inlet terminal 11, an outlet terminal 12, and an isolation contact, wherein the isolation contact is connected between the inlet terminal 11 and the outlet terminal 12. The detection module 20 is connected to the first housing 101 and comprises an outlet terminal 21 and an outlet plate 22. A connecting wire 23 is connected to the outlet plate 22, and the connecting wire 23 is electrically connected to the outlet terminal 12.
[0056] The input terminal 11 and the output terminal 21 are both used to electrically connect to the main circuit, so that the switch body 10 and the detection module 20 are connected in series in the main circuit. The detection module 20 is used to detect the signal parameters of the main circuit, and the switch body 10 is used to control the connection or disconnection of the main circuit through the isolation contact.
[0057] In the embodiment of the present application, the isolating switch 100 includes a switch body 10 and a detection module 20. Therefore, when the isolating switch 100 is connected to the main circuit, the isolating switch 100 can be operated to activate the switch body 10 to disconnect or connect the main circuit.
[0058] The detection module 20 can collect signal parameters in the main circuit and complete the detection of the signal parameters so that the user can know the working status of the main circuit.
[0059] The detection module 20 is connected to the switch body 10 to form the isolating switch 100. Therefore, the isolating switch 100 proposed in this application can have the functions of the switch body 10 and the detection module 20, taking into account the circuit on-off function and the signal parameter detection function.
[0060] In this way, it is convenient to manage the equipment in the main circuit according to the working conditions of the main circuit, and it is convenient to realize intelligent and digital power consumption through the isolation switch 100.
[0061] Among them, the signal parameters may include at least one of current, voltage, frequency, power factor, electric energy, etc. The specific type of the signal parameters is not specifically limited in the embodiment of the present application.
[0062] In the embodiment of the present application, the switch body 10 includes a first housing 101 and functional components. The functional components are arranged inside the first housing 101. The first housing 101 can protect the functional components and ensure the normal operation of the functional components.
[0063] Functional components are the components within the switch body 10 that disconnect the circuit. Specifically, these components can be the aforementioned isolating contacts. These are connected between the incoming and outgoing terminals 11 and 12. In the event of a main circuit anomaly, they can switch the current between the incoming and outgoing terminals 11 and 12, effectively switching the main circuit.
[0064] The isolating contact is the main component for cutting off the current, and includes two parts that can be in contact or separated to realize the opening or closing of the switch body 10, thereby controlling the main circuit to be connected or disconnected.
[0065] Specifically, the isolation contact may include a moving contact, a stationary contact, etc. For the specific structure of the isolation contact, reference may be made to the switch device in the prior art, and the embodiments of the present application will not be described in detail here.
[0066] In this application, the detection module 20 is connected to the switch body 10, specifically, the detection module 20 is connected to the first housing 101. In this way, the switch body 10 and the detection module 20 can be integrated and connected to the meter box as one component, which is convenient for wiring.
[0067] The main circuit may have a first connection terminal and a second connection terminal, wherein the first connection terminal is located near the positive electrode. When the disconnector 100 is located in the main circuit, the input terminal 11 may be connected to the first connection terminal, and the output terminal 21 may be connected to the second connection terminal, so as to connect the disconnector 100 in series in the main circuit.
[0068] Inside the isolating switch 100 , the outlet terminal 12 of the switch body 10 can be electrically connected to the connecting wire 23 on the detection module 20 , so that the switch body 10 and the detection module 20 can be connected in series, thereby reducing the possibility of the switch body 10 losing its function.
[0069] It should be noted that the detection module 20 and the first shell 101 can be connected in different ways, for example, bonding, welding, snapping or screwing, etc. The specific connection method between the detection module 20 and the first shell 101 is not specifically limited in the embodiment of the present application.
[0070] In some embodiments, as Figure 2 、 Figure 3 as well as Figure 4 As shown, the detection module 20 may include a second housing 201 and a main body. The main body is disposed within the second housing 201, and the outlet terminal 21 and the outlet plate 22 are disposed on the main body. A wire outlet hole 202 is provided on the side of the second housing 201 facing the first housing 101. The wire outlet hole 202 extends through the second housing 201. A portion of the connecting wire 23 extends from the second housing 201 through the wire outlet hole 202 and is electrically connected to the outlet terminal 12.
[0071] In the embodiment of the present application, the detection module 20 includes a second shell 201 and a main body. The second shell 201 can protect the main body to ensure that the main body can work normally.
[0072] When the detection module 20 includes the second housing 201, the connection between the detection module 20 and the first housing 101 can be specifically the connection between the second housing 201 and the first housing 101. This can reduce the possibility of damage to the switch body 10 or the detection module 20 itself when the detection module 20 is connected to the switch body 10.
[0073] At this time, a wire outlet hole 202 may be provided on the second shell 201 . Since the wire outlet hole 202 passes through the second shell 201 , the internal space of the second shell 201 and the external space may be communicated through the wire outlet hole 202 .
[0074] In this way, the connecting wire 23 can be connected to the outlet plate 22 on the main body and extend out of the second housing 201 through the outlet hole 202 to be connected to the switch body 10.
[0075] Since the wire outlet hole 202 is provided on the side of the second housing 201 facing the first housing 101, the wire outlet hole 202 is provided close to the first housing 101. This allows the connecting wire 23 to extend from the second housing 201 close to the first housing 101, facilitating connection between the connecting wire 23 and the outlet terminal 12 and reducing the possibility of the connecting wire 23 becoming tangled or tangled when the distance between the connecting wire 23 and the outlet terminal 12 is long.
[0076] In some embodiments, as Figure 2 and Figure 5As shown, the isolating switch 100 may further include a cover body 30, a first snap-fitting structure 24 is provided on the first shell 101 and / or the second shell 201, a second snap-fitting structure 31 is provided on the cover body 30, and the first snap-fitting structure 24 is snap-fitted with the second snap-fitting structure 31 so that the cover body 30 is covered on the outlet terminal 12 and shields the connecting line 23.
[0077] Since the detection module 20 is connected to the switch body 10 via the connection line 23 , the connection line 23 needs to be exposed for the detection module 20 to be integrated with the switch body 10 .
[0078] Thus, when the switch body 10 and the detection module 20 are connected to form the isolating switch 100 , a portion of the connecting wire 23 is exposed.
[0079] In the embodiment of the present application, a cover 30 is provided over the outlet terminal 12. Since the cover 30 shields the connecting wires 23, the possibility of electric shock caused by the exposed connecting wires 23 is reduced. Furthermore, the cover 30 protects the connecting wires 23, preventing them from being pulled and damaged during inspection or maintenance of equipment in the meter box.
[0080] When the cover 30 is set, the cover 30 can be snap-fitted with both the switch body 10 and the detection module 20 . This makes the cover 30 more stable and reduces the possibility of the cover 30 falling off due to unstable snap-fitting.
[0081] Of course, the cover 30 may also be only engaged with the switch body 10 or the detection module 20 . The specific configuration of the cover 30 is not specifically limited in this embodiment of the application.
[0082] The first shell 101 and / or the second shell 201 is provided with a first snap-fit structure 24 , and the cover body 30 is provided with a second snap-fit structure 31 . The first snap-fit structure 24 can be snap-fitted with the second snap-fit structure 31 to achieve installation of the cover body 30 .
[0083] In the present application, the first clamping structure 24 may be provided on one of the first shell 101 and the second shell 201 , so that the cover 30 may be clamped with one of the first shell 101 and the second shell 201 .
[0084] Alternatively, the first housing 101 and the second housing 201 may both be provided with the first snap-fitting structures 24. In this case, the cover 30 may be provided with a plurality of second snap-fitting structures 31. Some of the second snap-fitting structures 31 may snap-fit with the first snap-fitting structures 24 on the first housing 101, while other parts of the second snap-fitting structures 31 may snap-fit with the first snap-fitting structures 24 on the second housing 201, thereby improving the reliability of the installation of the cover 30.
[0085] As a preferred method, Figure 5 As shown, the first engaging structure 24 can be provided on the second housing 201. This reduces the need for modifications to the switch body 10. When forming the isolating switch 100 proposed in this application, a conventional switch can be directly used as the switch body 10, and the detection module 20 can be connected to the housing, which is relatively convenient.
[0086] In the embodiment of the present application, the first snap-fit structure 24 and the second snap-fit structure 31 can be arranged in different ways. Here, the first snap-fit structure 24 is arranged on the second housing 201 as an example. The manner in which the first snap-fit structure 24 is arranged on the first housing 101 can be referred to in the following description and will not be further described in the embodiment of the present application.
[0087] like Figure 5 As shown, a mounting member 203 may be connected to a side of the second housing 201 facing away from the outlet terminal 21 , and a mounting groove may be provided on a side of the mounting member 203 facing the first housing 101 .
[0088] The bottom of the mounting groove may have a clamping hole, and the clamping hole may form a first clamping structure 24 .
[0089] The cover 30 may be provided with a snap-fitting boss on the side facing the second housing 201, and the snap-fitting boss may form a second snap-fitting structure 31. When installing the cover 30, the side facing the second housing 201 may be extended into the mounting groove so that the snap-fitting boss is embedded in the snap-fitting hole to complete the snap-fitting.
[0090] Alternatively, the bottom of the mounting groove may have a clamping protrusion, and the clamping protrusion may form the first clamping structure 24 .
[0091] A snap-fitting groove is provided on the outer wall of the cover body 30 on the side facing the second shell 201, and the snap-fitting groove can form a second snap-fitting structure 31. When installing the cover body 30, the side of the cover body 30 facing the second shell 201 can be extended into the installation groove so that the snap-fitting groove is sleeved on the outside of the snap-fitting protrusion to complete the snap-fitting.
[0092] Of course, the first clamping structure 24 and the second clamping structure 31 may also be other structures that can cooperate with each other to achieve clamping. The specific structures of the first clamping structure 24 and the second clamping structure 31 are not specifically limited in this embodiment of the application.
[0093] In some embodiments, as Figure 3 As shown, the incoming terminal 11 and the outgoing terminal 21 are located on the same side.
[0094] In this way, the incoming and outgoing lines of the isolating switch 100 are located on the same side. When the isolating switch 100 is connected to the main circuit, the first connection end and the second connection end can be connected on the same side, which can facilitate wiring.
[0095] In addition, refer to Figure 3 The input terminal 11 and the output terminal 12 of the switch body 10 are located on opposite sides of the switch body 10 , and the output terminal 21 and the output plate 22 of the detection module 20 are also located on opposite sides of the detection module 20 .
[0096] Since the incoming terminal 11 and the outgoing terminal 21 are located on the same side in the present application, the outgoing terminal 12 and the outgoing board 22 can also be located on the same side.
[0097] In this way, the connecting wire 23 is also located on one side of the outlet terminal 12, which can facilitate the electrical connection between the connecting wire 23 and the outlet terminal 12, and can reduce the situation where the connecting wire 23 needs to bypass part of the detection module 20 between the outlet plate 22 and the outlet terminal 21 when connecting the connecting wire 23 to the outlet terminal 12. It can also reduce the length of the connecting wire 23 and reduce the possibility of the connecting wire 23 being entangled.
[0098] In some embodiments, the main circuit has a power supply terminal and a load terminal. When the main circuit is connected, current flows from the power supply terminal to the load terminal. At the disconnector 100, current flows from the input terminal 11 to the output terminal 21.
[0099] The main circuit has a power supply end and a load end. Current can flow from the power supply end to the load end to provide power to the devices on the current flow path so that these devices can work normally.
[0100] The isolating switch 100 is disposed in the main circuit, and the isolating switch 100 can also receive electrical energy, so that the switch body 10 and the detection module 20 can be powered and operate normally.
[0101] In the embodiment of the present application, since the current flows in the direction from the input terminal 11 to the output terminal 21, the switch body 10 can be arranged at the front end of the detection module 20. In this way, the switch body 10 is arranged between the detection module 20 and the power supply end, and the switch body 10 can play the role of isolation and disconnection.
[0102] In other words, when the switch body 10 is disconnected, the detection module 20 behind the switch body 10 can also be isolated from the power supply end. This can reduce the possibility that the switch body 10 cannot isolate the detection module 20 from the power supply end when the detection module 20 is arranged at the front end of the switch body 10.
[0103] It should be noted that the first connection end is close to the power supply end, and the second connection end is far away from the power supply end. When the isolation switch 100 is connected to the second connection end through the first connection end, current flows from the first connection end to the second connection end.
[0104] In the embodiment of the present application, the detection module 20 is connected to a side of the first housing 101 away from the power end.
[0105] With the above arrangement, the detection module 20 is away from the power supply terminal, and the switch body 10 is close to the power supply terminal. In this way, the relative position relationship between the switch body 10 and the detection module 20 can correspond to the flow direction of the current.
[0106] Based on this, when the isolating switch 100 is connected to the main circuit, the first connection end is close to the switch body 10 and the second connection end is close to the detection module 20, which can facilitate the connection of the isolating switch 100 to the main circuit and reduce the possibility of the wires going around during the connection process.
[0107] In actual application, when the device is connected to the main circuit, the device is generally connected to the left end with the line in and the right end with the line out. In the embodiment of the present application, the detection module 20 can be set on the right side of the switch body 10 so that the isolation switch 100 is connected to the main circuit, such as Figure 1 and Figure 3 shown.
[0108] In some embodiments, as Figure 1 、 Figure 6 and Figure 7 As shown, the detection module 20 also includes a circuit board 25 having a first terminal 251 and a second terminal 252. The first terminal 251 is connected to the connecting line 23, and the second terminal 252 is connected to the external circuit. The main body is electrically connected to the circuit board 25, and the circuit board 25 is used to power the main body so that the main body can detect the signal parameters of the main circuit. The voltage of the external circuit to ground is zero.
[0109] In the embodiment of the present application, the detection module 20 further includes a circuit board 25 , which can supply power to the main body so that the main body can work and detect the signal parameters of the main circuit.
[0110] The circuit board 25 has a first terminal 251 and a second terminal 252 . The first terminal 251 and the second terminal 252 can be connected to the connecting wire 23 and the external circuit respectively.
[0111] In this way, the connecting wire 23 and the external circuit can cooperate to form a loop, providing an operating voltage for the circuit board 25, thereby enabling the circuit board 25 to supply power to the main body.
[0112] It should be noted that in a normal power usage environment, there will be a live wire and a neutral wire. The voltage of the live wire to the ground is 220V-230V, and the voltage of the neutral wire to the ground is zero.
[0113] In order to make the isolating switch 100 disconnect the circuit and ensure that the circuit is de-energized in abnormal situations or during maintenance, it needs to be connected to the live wire to ensure user safety. That is, the signal flowing in the switch body 10 and the detection module 20 is transmitted by the live wire.
[0114] That is, the main circuit is the live wire and the external circuit is the neutral wire. In this way, the circuit board 25, the live wire and the neutral wire can form a loop together so that the voltage of the live wire and the neutral wire can be applied to the circuit board 25, making the circuit board 25 work.
[0115] In addition, the circuit board 25 is connected to the connecting wire 23, and the circuit board 25 can also be connected to the rear side of the switch body 10. In this way, when the switch body 10 is working and the main circuit is disconnected, the circuit board 25 on the rear side can also lose power, thereby improving the safety of the circuit board 25.
[0116] It should also be noted that the first terminal 251 and the connecting line 23 can be connected through a first wire 253 , and the second terminal 252 and the external circuit can be connected through a second wire 254 .
[0117] Since the second terminal 252 is to be connected to an external circuit, the second wire 254 is to extend from the second housing 201 .
[0118] In order to reduce the possibility that the second wire 254 is pulled during use or maintenance of the disconnector 100 , causing the second wire 254 to exert force on the second terminal 252 and damage the second terminal 252 , the second wire 254 may have a surrounding portion inside the second housing 201 .
[0119] In this way, when the second wire 254 is pulled, the surrounding portion thereof can be deformed, so that the size of the loop formed by the surrounding portion changes, thereby reducing the possibility of the second wire 254 directly acting on the second terminal 252 .
[0120] In addition, the second wiring terminal 252 may have two wiring positions: an input line and an output line, and both wiring positions may be connected to an external line.
[0121] Similarly, the first wiring terminal 251 may also have two incoming and outgoing wiring positions, and both wiring positions may be connected to the connecting line 23 .
[0122] In some embodiments, as Figures 1 to 3 、 Figure 6As shown, the main body includes a terminal structure 204, a magnetic ring 26, and a winding 261. The terminal structure 204 is connected to the second housing 201. The outlet terminal 21 and the outlet plate 22 are both located on the terminal structure 204. The winding 261 is wound around the magnetic ring 26, and the magnetic ring 26 is sleeved on the connecting wire 23. Both ends of the winding 261 are electrically connected to the circuit board 25. The winding 261 is used to generate an induction signal based on the current flowing through the connecting wire 23.
[0123] Through the above configuration, the detection module 20 can specifically detect the signal parameters of the main circuit through the magnetic ring 26 and the winding 261 .
[0124] When the isolating switch 100 connects the main circuit, current will flow from the first connection end to the second connection end through the connection line 23 , and thus current can flow in the connection line 23 .
[0125] Since the winding 261 is electrically connected to the circuit board 25, the circuit board 25 can supply power to the winding 261, so that the winding 261 and the magnetic ring 26 can form a magnetic field. When current flows through the connecting wire 23, the two ends of the winding 261 can induce an induction signal based on the principle of electromagnetic induction.
[0126] In this way, the signal parameters of the main loop can be calculated based on the sensing signal.
[0127] In some embodiments, a controller may be connected to the circuit board 25 , and both ends of the winding wire are electrically connected to the controller.
[0128] In this way, the controller can receive the sensing signal and calculate the signal parameters of the main circuit based on the sensing signal, completing the detection of the main circuit. Based on this, it is convenient for users to understand the signal parameters of the main circuit and manage the devices in the main circuit.
[0129] Specifically, different voltage signals can be induced at both ends of the winding 261 according to the different currents flowing in the connecting wire 23. After receiving the voltage signal, the controller can calculate the current value in the connecting wire, that is, the current value of the main circuit.
[0130] In the embodiments of the present application, in some embodiments, a communication unit is further provided in the detection module, the communication unit is electrically connected to the controller and is communicatively connected to the server, and the controller is used to transmit the signal parameters to the server.
[0131] The setting of the communication unit can connect the controller with the server, so that the control chip can transmit the calculated signal parameters to the server, and the server performs subsequent processing, such as sending it to the management personnel, etc.
[0132] Of course, the communication connection between the controller and the server can also facilitate sending instructions to the controller. For example, after checking the signal parameters, the user finds that a certain parameter is abnormal. At this time, the user can send an instruction to the control chip, which will control the magnetic ring 26 or other structures to re-collect data, etc., so as to realize intelligent management.
[0133] It should be noted that the communication unit may specifically be a 4G or 5G antenna 28, such as Figure 6 Of course, it can also be a structure that can establish a communication channel for a Bluetooth module, a wireless communication module, etc. The specific structure of the communication unit is not specifically limited in this embodiment of the application.
[0134] It should also be noted that, in addition to the aforementioned controller being responsible for calculating signal parameters, sending instructions, and communicating with the server, multiple controllers may also be provided, with one controller being responsible for calculating signal parameters, another controller being responsible for sending instructions and communicating with the server, and so on.
[0135] In some embodiments, a working device may be provided on the circuit board 25 , and the working device cooperates with the main body to detect the signal parameters of the main circuit.
[0136] According to the above description, the magnetic ring 26 can sense the current flowing in the connecting line 23 and generate a sensing signal, and then transmit the sensing signal to the controller so that the controller can calculate the current value of the main circuit.
[0137] Other signal parameters, such as the frequency of the main circuit, the voltage of the main circuit, etc., can be collected through the working devices provided on the circuit board 25.
[0138] For example, the circuit board 25 may be provided with working devices such as a detection circuit and a frequency meter, and these working devices may also be connected to the controller. In this way, the controller may also receive the detection results of the working devices and calculate other types of signal parameters of the main circuit.
[0139] In this way, the controller can perform calculations based on the detection results of the working device and the induction signal generated by the magnetic ring 26, which can make the signal parameter results more accurate and increase the types of parameters in the signal parameters, making the detection more comprehensive.
[0140] In the embodiments of this application, Figure 6 、 Figure 8 and Figure 9 As shown, the main body further includes an isolation seat 27, which is connected to the circuit board 25 and covers at least part of the working device.
[0141] Through the above arrangement, the working device can be isolated from the main body through the isolation seat 27, thereby increasing the insulation between the working device and the main body and reducing the mutual influence between the components on the circuit board 25 and the main body.
[0142] It should be noted that the outlet terminal 21 is connected to the main circuit, which makes the current signal and voltage signal at the outlet terminal 21 larger. Correspondingly, the terminal structure 204 there has a greater impact on the circuit board 25 and the working components on the circuit board 25.
[0143] Therefore, the isolation seat 27 can be set on the circuit board 25 and opposite to the terminal structure 204 to isolate the terminal structure 204 from the circuit board 25 and reduce the impact of the terminal structure 204 on the operation of the circuit board 25.
[0144] In addition, the isolation seat 27 can also be covered on the controller to ensure the normal operation of the controller.
[0145] In addition, since the isolation seat 27 has an isolation function, the distance between the circuit board 25 and the terminal structure 204 can also be reduced, so that the circuit board 25 and the terminal structure 204 can work normally even when the distance between them is small, thereby reducing the volume of the detection module 20, making the internal layout of the detection module 20 compact and reasonable, and reserving more layout space for the circuit board 25 and working devices.
[0146] In addition, the isolation seat 27 can also serve as a fixing device, on which a wire clamp can be provided. The connecting wire 23 can be fixed to the isolation seat 27 by the wire clamp to reduce the shaking of the connecting wire 23 in the disconnector 100.
[0147] It should also be noted that the terminal structure can be the same as the existing terminal structure, including a wiring baffle, an adjustment screw, and a wiring frame. When wiring is required, the adjustment screw can be loosened to offset the wiring baffle and the wiring frame. The wire can then be placed in the wiring frame and the screw can be tightened to complete the wiring.
[0148] The wiring frame can also be fixed by the isolation seat 27, which can reduce the possibility of needing to set up other additional fixing devices.
[0149] Of course, the outlet terminal 21 can also be connected to the wire in other ways, such as a copper busbar.
[0150] In addition, at the switch body 10, the input terminal 11 and the output terminal 12 of the switch body 10 can also be the above-mentioned terminal structure, such as Figure 10 As shown, Figure 10The structure of the outgoing terminal 12 is shown. In this way, the modification can be reduced, and the switch in the related art can be directly used as the switch body 10, and the detection module 20 is connected thereon to form the isolating switch 100 of the present application, which is convenient to manufacture and can reduce the cost.
[0151] Of course, the switch in the related art can be improved, and the terminal connected to the loop is improved to be other structures that can be connected to the wire, such as a copper bar, a connector, and the like, which is not limited in the present application.
[0152] In addition, the second shell 201 includes a base and a cover plate, and the base and the cover plate are buckled to form the second shell 201. The main body, the connecting wire 23, the circuit board 25, the isolation seat 27, and the like can be arranged in the space formed by buckling the base and the cover plate.
[0153] In the embodiment of the present application, the switch body 10 can realize the breaking or closing of the main loop. The detection module 20 can collect the signal parameters in the main loop and complete the detection of the signal parameters, so that the user can know the working condition of the main loop.
[0154] That is, the isolating switch 100 provided in the present application can consider the on-off function of the loop and the detection function of the signal parameters. In this way, the equipment in the main loop can be managed according to the working condition of the main loop, and the intelligentization and digitization of power utilization can be realized through the isolating switch 100.
[0155] Finally, it should be noted that: the above embodiments are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
