Description

It is necessary to discharge the capacitor through a discharge device or other structure to reduce the possibility of safety problems caused by the residual voltage.

[0003] Currently, discharge devices can be connected to the capacitor's pins via wire clamps to discharge the capacitor. However, using wire clamps for discharge poses certain safety hazards, making the use of such devices less safe. Utility Model Content

[0030] The discharge device includes a mounting component that provides space for sockets and a discharge resistor. Two sockets are spaced apart and embedded in the mounting component, while the discharge resistor is housed within the mounting cavity of the component. Each end of the discharge resistor is electrically connected to a socket, ensuring current flow between each socket and the discharge resistor. The discharge device also includes two cables, each with a plug at one end for insertion into a socket and an alligator clip at the other end. When discharging devices with residual voltage, such as capacitors, the plugs of the two cables are inserted into the two sockets, and the alligator clips at the other ends of the cables are connected to the two leads of the capacitor. Because of the residual voltage in the capacitor, a discharge circuit is formed between the two leads, the two cables, the two sockets, and the discharge resistor.

After the residual voltage in the capacitor is released, the cable plugs can be removed from the sockets, and the alligator clips can be separated from the capacitor. When the capacitor does not need to discharge, the cable and socket do not need to be connected. The cable can be collected and stored. The collected cable is not easily worn, which reduces the impact of cable wear on discharge safety. The cable and socket can be separated, which also reduces the possibility of accidental contact between the alligator clips of the two cables, thus reducing the safety hazards. All of these factors help improve the safety of the discharge device and, to a certain extent, solve the technical problem of insufficient safety in the use of the discharge device.

[0037] It should be noted that all directional indications in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0038] In related technologies, a discharge device can be connected to the capacitor's pins via a wire clamp to discharge the capacitor. However, the wire clamp is usually fixed in position and exposed to the outside environment. On the one hand, the wire clamp may unintentionally conduct electricity to a conductive structure, potentially affecting the safety of the operator. On the other hand, the wire clamp is also prone to wear, and a worn wire clamp may result in incomplete discharge during the discharge process, posing a certain safety hazard to the capacitor discharge process. Therefore, the discharge device is not safe to use. This application provides a discharge device that can at least partially solve the above-mentioned technical problems.

[0039] The present application will now be described in conjunction with the accompanying drawings:

[0040] Figure 1 This application shows a schematic diagram of the structure of a discharge device in some or certain embodiments. Figure 2 This application shows a schematic diagram of the internal structure of a discharge device according to some or all embodiments thereof, with reference to... Figure 1 , 2 This application provides a discharge device, including:

[0041] Mounting component 1 has a mounting cavity;

[0042] Two sockets 2 are embedded in the mounting piece 1 at intervals;

[0043] The discharge resistor 3 is located in the mounting cavity, and its two ends are electrically connected to a socket 2 respectively;

[0044] Two cables 4, one end of which is a plug 41 for corresponding insertion into a socket 2, and the other end of which is an alligator clip 42.

[0045] The mounting component 1 in the discharge device provides installation space for the sockets 2 and the discharge resistor 3. Two sockets 2 are spaced apart and embedded in the mounting component 1. The discharge resistor 3 is located in the mounting cavity of the mounting component 1, and each end of the discharge resistor 3 is electrically connected to one of the sockets 2. Current can flow between each socket 2 and the discharge resistor 3. The discharge device also includes two cables 4. One end of each cable 4 is a plug 41, used to connect to a corresponding socket 2, and the other end is an alligator clip 42. When it is necessary to discharge devices with residual voltage, such as capacitors, the plugs 41 of the two cables 4 can be connected one-to-one to the two sockets 2. The alligator clips 42 at the other end of the two cables 4 can be connected one-to-one to the two pins of the capacitor. Because the capacitor has residual voltage, a discharge circuit can be formed between the two pins of the capacitor, the two cables 4, the two sockets 2, and the discharge resistor 3. The voltage is released through the discharge resistor 3. After the residual voltage in the capacitor is released, the plugs 41 of the cables 4 can be pulled out of the sockets 2, and the alligator clips 42 can be separated from the capacitor. When the capacitor does not need to discharge, cable 4 and socket 2 do not need to be connected. Cable 4 can be collected and stored. The collected cable 4 is not easily worn, which can reduce the impact of cable 4 wear on discharge safety. Cable 4 and socket 2 can be separated, which can also reduce the possibility of accidental contact and connection of the alligator clips 42 of the two cables 4, thus creating a safety hazard. All of these are conducive to improving the safety of the discharge device and, to a certain extent, solving the technical problem of insufficient safety in the use of the discharge device.

[0046] It should be noted that when socket 2 is electrically connected to discharge resistor 3, socket 2 and discharge resistor 3 can conduct. When plug 41 is inserted into socket 2, plug 41 and socket 2 can conduct. When plug 41 and socket 2 are conducting, plug 41 and discharge resistor 3 can also conduct. Figure 1 The plug 41 of cable 4 is disconnected from socket 2. Figure 1 and Figure 2 The image does not directly indicate the installation cavity. Figure 2 The structure shown is a schematic diagram of one deployed state of the discharge device. Figure 2 The space used to place the discharge resistor 3 is the mounting groove 111 mentioned below, which is used to form a mounting cavity.

[0047] In some or more embodiments, the alligator clip 42 is an alligator clip 42 with an insulating sleeve 421, and the discharge device further includes:

[0048] Two insulating sleeves 5 are fitted onto the two plugs 41 in a corresponding manner.

[0049] The alligator clip 42 has an insulating sleeve 421, which can improve the safety of the operator during the operation of the alligator clip 42. The plug 41 of the cable 4 can also be fitted with a corresponding insulating sleeve 5. When the plug 41 of the cable 4 is not in use, the insulating sleeve 5 can be put on the plug 41 to prevent the plug 41 from accidentally conducting, thereby improving the protection effect of the cable 4 and improving the safety of the discharge device.

[0050] In some or more embodiments, the insulating sleeve 421 of the alligator clip 42 can be a rubber insulating sleeve 421, and the insulating sheath 5 can also be a rubber insulating sleeve 421. This is low-cost, easy to implement, and when the plug 41 of the cable 4 is needed, the plug 41 can be pulled out from the insulating sheath 5.

[0051] In some or more embodiments, the plug 41 is a banana plug, and the socket 2 is a banana socket that mates with the banana plug. This facilitates the connection and conduction between the plug 41 and the socket 2.

[0052] In some or more embodiments, the mounting member 1 is an insulating mounting member 1, and the surface of the mounting member 1 has an insulating coating. This reduces the possibility of the mounting member 1 itself becoming conductive, thereby improving the safety of the discharge device.

[0053] It should be noted that the insulating mounting component 1 is a mounting component 1 made of insulating material, and the surface of the mounting component 1 is coated with insulating paint to form an insulating coating.

[0054] In some or more embodiments, mounting component 1 may include:

[0055] The mounting part 11 is provided with a mounting groove 111 and a winding post 112 located in the mounting groove 111. The discharge resistor 3 is provided in the mounting groove 111 and is spaced apart from the winding post 112.

[0056] The closing part 12 is hinged to the mounting part 11 and covers the opening of the mounting groove 111 to form a mounting cavity;

[0057] The first locking part 13 is connected to the mounting part 11;

[0058] The second locking part 14 (not shown in the figure) is connected to the closing part 12 and is used to engage with the first locking part 13.

[0059] The mounting groove 111 of the mounting part 11 in the mounting component 1 provides mounting space for the discharge resistor 3. The sealing part 12 is hinged to the mounting part 11 and covers the opening of the mounting groove 111 to form a mounting cavity. The discharge resistor 3 is located in the mounting cavity, allowing the sealing part 12 to rotate relative to the mounting part 11, opening the mounting groove 111 for easy installation and removal of the discharge resistor 3. The discharge resistor 3 is spaced apart from the winding post 112. When discharge is not required, the sealing part 12 can be opened relative to the mounting part 11, the cable 4 can be wound around the winding post 112, and then the sealing part 12 can be re-covered in the opening of the mounting groove 111. The first locking part 13 and the second locking part 14 engage to lock the sealing part 12 and the mounting part 11. This facilitates the movement and carrying of the discharge device and provides good protection for the cable 4.

[0060] In some or more embodiments, the mounting portion 11 may be an insulated mounting portion 11, the sealing portion 12 may be an insulated sealing portion 12, and the winding post 112 may also be an insulated winding post 112. The mounting portion 11 may be provided with an insulating enclosure 113 that surrounds multiple winding posts 112. The cable 4 can be confined within the space surrounded by the insulating enclosure 113.

[0061] In some or more embodiments, the mounting portion 11 may be a box with an opening on one side, and the internal space of the mounting portion 11 forms a mounting groove 111. The closing portion 12 may be a rectangular plate, and one side of the closing portion 12 may be hinged to the mounting portion 11 via a hinge. The first locking portion 13 may be a fixed part of a latch, and the second locking portion 14 may be a movable part of a snap-fit. This facilitates fabrication and implementation. The socket 2 may pass through the closing portion 12, and when the closing portion 12 closes the mounting groove 111 to form a mounting cavity, a portion of the socket 2 may be located in the mounting cavity and electrically connected to the discharge resistor 3.

[0062] In some or more embodiments, the discharge resistor 3 has a metal casing, and the mounting component 1 is provided with an insulating plate 15 surrounding the discharge resistor 3. One end of the discharge resistor 3 is electrically connected to a corresponding socket 2 via a cable, which can pass through the insulating plate 15. It should be noted that due to space limitations in the figure, the cable is not shown.

[0063] The discharge resistor 3, with its metal casing, efficiently converts electrical energy into heat, quickly dissipating the voltage and thus improving the discharge efficiency of the device. The mounting component 1 has an insulating plate 15 surrounding the discharge resistor 3 to prevent accidental contact and enhance the safety of the device. One end of the discharge resistor 3 is electrically connected to the corresponding socket 2 via a cable, and the cable passes through the insulating plate 15 without affecting the normal conduction between the discharge resistor 3 and the socket 2.

[0064] It should be noted that the discharge resistor 3 can be a conductor with a certain resistance. The discharge resistor 3 can be fixed to the mounting part 11 by welding or connected to the mounting part 11 by a bracket.

[0065] In some or more embodiments, the mounting component 1 is provided with a ventilation hole 16 communicating with the mounting cavity. For the discharge resistor 3 that converts electrical energy into heat energy, the ventilation hole 16 can play a certain heat dissipation role, prevent the temperature inside the mounting cavity from becoming too high, and also help improve the safety of the discharge device.

[0066] In some or more embodiments, the ventilation hole 16 may be provided in the mounting portion 11 and communicate with the mounting groove 111. When the opening of the mounting groove 111 is closed by the sealing portion 12, the ventilation hole 16 can dissipate heat for the discharge resistor 3 in the mounting cavity. The insulating plate 15 may be provided in the mounting groove 111 of the mounting portion 11, or it may be an integral structure with the mounting portion 11. The mounting portion 11 of the mounting member 1 may also be provided with a handle 100 for easy carrying of the discharge device.

[0067] In some or more embodiments, the discharge device further includes:

[0068] A DC voltmeter 6 is embedded in the connecting mounting piece 1 and connected in parallel with the discharge resistor 3;

[0069] A series resistor 7 is located in the mounting cavity and is connected in series with a DC voltmeter 6;

[0070] A fuse 8 is located in the mounting cavity and is connected in series with a discharge resistor 3. One end of the discharge resistor 3 is electrically connected to a socket 2 through the fuse 8.

[0071] A DC voltmeter 6 is connected in parallel with a discharge resistor 3 to measure the voltage across the discharge resistor 3. The voltage across the discharge resistor 3 provides feedback on the residual voltage of the capacitor. Based on the reading of the DC voltmeter 6, it can be determined whether the residual voltage of the capacitor has been completely released. The series resistor 7 connected in series with the DC voltmeter 6 improves the safety of the DC voltmeter 6. The fuse 8 can melt at high temperatures, both of which improve the safety of the discharge device.

[0072] It should be noted that both parallel and series connections are achieved via cables. Individual resistors can be connected together in series, parallel, or a combination of both to form a series resistor 7. When a DC voltmeter 6 is installed, one socket 2 will be connected to the positive terminal of the DC voltmeter 6, and the other socket 2 will be connected to the negative terminal. The two sockets 2 can be marked with "p" to indicate the positive terminal and "n" to indicate the negative terminal. Alternatively, the two cables 4 can be made different in color or size to distinguish between the positive and negative terminals. The DC voltmeter 6 can also be embedded in the enclosure 12.

[0073] In some or more embodiments, the discharge device further includes:

[0074] A push-button switch 9 is mounted on mounting bracket 1 and is used to control the connection and disconnection between fuse 8 and a socket 2.

[0075] The operator can control the connection and disconnection between fuse 8 and socket 2 using push-button switch 9. Push-button switch 9 can be a normally open switch. After cable 4 is connected to the capacitor pins, pressing push-button switch 9 connects fuse 8 and socket 2, allowing current to flow to discharge resistor 3, where it is dissipated. After the capacitor voltage has been released, pressing the switch again disconnects the current between fuse 8 and socket 2. Here, "connection and disconnection" refers to the flow of current between fuse 8 and socket 2.

[0076] In some or more embodiments, the push-button switch 9 may also be a self-locking switch. The discharge process is relatively stable.

[0077] In some or more embodiments, the discharge device further includes:

[0078] Indicator light 10 is installed on mounting bracket 1 and is used to provide feedback on the on / off status between fuse 8 and a socket 2.

[0079] When fuse 8 is connected to socket 2, it indicates that the discharge circuit between discharge resistor 3 and capacitor is connected. Discharge resistor 3 is consuming the residual voltage of capacitor, and indicator light 10 can light up as an indication that the discharge device is working normally. When fuse 8 is disconnected from socket 2, indicator light 10 can turn off, indicating that the discharge device is not working. Indicator light 10 can be installed in the enclosure 12.

[0080] In some or more embodiments, the fuse 8 can be mounted to the mounting part 11 of the mounting member 1 via a base, and the mounting method of the series resistor 7 can refer to the mounting method of the discharge resistor 3.

[0081] Figure 3 The circuit diagram of a discharge device in some or certain embodiments of this application is shown. (Refer to...) Figure 3 From this, we can see the relationship between fuse 8, discharge resistor 3, DC voltmeter 6, series resistor 7 and push-button switch 9. Figure 3 The symbol p indicates the socket 2 with the positive terminal of the DC voltmeter 6, and n indicates the socket 2 with the negative terminal of the DC voltmeter 6.

[0082] It should be noted that, Figure 3 Indicator light 10 is not shown in the diagram. Indicator light 10 can also be connected to the push-button switch 9 and the fuse 8 via a cable. Indicator light 10 will light up when powered.
