Description

Electrical equipment and temperature detection components

Technical Field

[0002] The present application relates to the field of power electronics, and in particular to an electrical device and a temperature detection component. Background Art

[0003] Currently, for high-current input or output of electrical equipment such as inverters or energy storage converters, the common solution on the wiring side is to crimp cables with round terminals or copper terminal blocks, and then tighten them to the terminal copper busbars with screws. However, the cables required for high-current connections are relatively thick, and the round terminal selection specifications have relatively large overcurrent capabilities. The terminal locking nuts and screws require a large torque value. During actual on-site installation, improper operation can easily lead to problems such as nuts and screws not being tightened or round terminals being loosely connected, resulting in a sharp increase in thermal resistance at the wiring location. After the equipment has been powered on and operated for a period of time, problems such as terminal burning, equipment failure or fire may occur, posing a major safety hazard and affecting the reliable operation of electrical equipment.

[0086] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0087] The following describes an electrical device and a temperature detection component according to an embodiment of the present application with reference to FIG1 to FIG9 .

[0091] As shown in FIG1 , the terminal device 2 , the temperature detection device 3 and the electronic components are all arranged in the cabinet 1 .

[0092] The wiring terminal device 2 is provided in the cabinet 1 . The wiring terminal device 2 is used to electrically connect the cables and the controller 4 . The cables and the wiring terminal device 2 are fastened by screws.

[0093] The temperature detection device 3 is provided at the terminal device 2 . The temperature detection device 3 is used to detect the temperature of the terminal device 2 and send a temperature detection feedback value to the controller 4 .

[0094] Electronic components are arranged in the cabinet 1 , and the electronic components may be reactors or fans, etc.

[0095] The controller 4 is electrically connected to the temperature detection device 3 and the terminal device 2 respectively. The controller 4 controls the temperature detection device 3 to collect data. The controller 4 can receive the temperature detection feedback value detected by the temperature detection device 3. If the temperature detection feedback value is higher than the preset value, the controller 4 can perform a fault warning and equipment shutdown protection.

[0096] In related technologies, when electrical equipment needs to input or output large currents, OT or DT crimped cables are usually used, and then they are fastened to the terminal copper busbars with screws. During the on-site installation process, improper operation often results in nuts and screws not being tightened or OT loose connections, which leads to a sharp increase in thermal resistance at the wiring position. Terminals are prone to burning, equipment failure or fire, posing a major safety hazard and affecting the reliable operation of electrical equipment.

[0097] According to the electrical equipment provided in the embodiment of the present application, by arranging a temperature detection device 3 on the terminal device 2, and electrically connecting the temperature detection device 3 to the controller 4, and the controller 4 to the terminal device 2, the controller 4 can perform fault warning and equipment shutdown protection actions based on the temperature detection feedback value of the temperature detection device 3, which can greatly improve the operating reliability of the electrical equipment and avoid the problem of overheating failure of the electrical connection position caused by improper on-site wiring operations.

[0098] The controller 4 and the terminal block device 2 can be installed in at least three ways:

[0101] By arranging the connection terminal device 2 inside the cabinet 1 , a protection effect can be achieved for the connection terminal device 2 .

[0102] Second, the controller 4 and the terminal device 2 are installed in different spaces.

[0103] In this embodiment, the terminal device 2 is arranged outside the cabinet 1. The cabinet 1 is provided with a wire threading hole. The terminal device 2 can have a protective structure. The terminal device 2 is arranged on the outer wall of the cabinet 1 for easy maintenance.

The other end of the transmission line 32 passes through the wire hole and is electrically connected to the controller 4.

[0105] Third, the controller 4 and the terminal block device 2 are both installed in the cabinet and in different spaces.

[0106] In this embodiment, as shown in FIG1 , the cabinet 1 includes: a main box 11 and a junction box 12 . The controller 4 is disposed in the main box 11 , and the terminal device 2 is installed in the junction box 12 .

[0107] As shown in FIG2 , the junction box 12 is installed on the main box body 11 , and the junction box 12 and the side wall of the main box body 11 can be connected by threaded connectors, welding, snap fasteners or other connection methods.

[0108] The terminal block device 2 is installed in the junction box 12 . The terminal block device 2 and the side wall of the junction box 12 can be connected by means of threaded connectors, snap fasteners, or other connection methods.

[0109] As shown in Figure 4, the temperature detection device 3 includes: a temperature detection component 31 and a transmission line 32. The temperature detection component 31 is arranged in the junction box 12. One end of the transmission line 32 is connected to the temperature detection component 31. The other end of the transmission line 32 passes through the junction box 12 and the main box body 11, and is electrically connected to the controller 4.

[0110] It can be understood that the controller 4 and the terminal device 2 are installed in different spaces, and the temperature detection device 3 is installed in the terminal device 2, that is, the controller 4 and the temperature detection device 3 are installed in different spaces, and the transmission line 32 electrically connected between the controller 4 and the temperature detection device 3 needs to pass through the side wall of the main box 11 and the side wall of the junction box 12.

[0111] The transmission line 32 can be a hard conductor such as copper, or a flexible cable. Alternatively, the front section connected to the temperature detection element 31 can be a hard conductor, and the rear section can be a flexible cable connected to the hard conductor.

[0112] The temperature detecting element 31 is provided on the wiring terminal device 2 , that is, the temperature detecting point is provided on the wiring terminal device 2 . The temperature detecting element 31 is used to detect the temperature of the wiring terminal device 2 .

[0113] In this embodiment, the transmission line 32 is used to pass through the junction box 12 and the main box 11 to electrically connect the temperature detection element 31 and the controller 4 .

[0114] The transmission line 32 passing through the junction box 12 and the main box 11 can be in at least two of the following structural forms:

[0115] First, as shown in FIG6 , a reserved hole 13 is provided in the main box 11 and the junction box 12 , and the other end of the transmission line 32 passes through the junction box 12 and the reserved hole 13 to be electrically connected to the controller 4 .

[0116] In this embodiment, the reserved hole 13 connects the main box 11 and the junction box 12 , the temperature detection element 31 is provided in the junction box 12 , and the transmission line 32 passes through the junction box 12 and the reserved hole 13 and is electrically connected to the controller 4 .

[0117] In some embodiments, the reserved hole 13 is located on a side wall of the junction box 12 that is not blocked by the terminal assembly 2 , so that the transmission line 32 can pass through the reserved hole 13 .

[0118] In some embodiments, the terminal block device 2 is provided with a through hole 211 communicating with the reserved hole 13 , and the other end of the transmission line 32 passes through the through hole 211 and the reserved hole 13 and is electrically connected to the controller 4 .

[0119] In this embodiment, the temperature detection element 31 is mounted on the terminal device 2 , and the transmission line 32 extends toward the via hole 211 .

[0120] Secondly, as shown in Figure 3, the main box 11 and the junction box 12 are both provided with docking through holes 14, which are used for electrically connecting the terminal device 2 to the controller 4; as shown in Figure 7, the terminal device 2 is provided with a through hole 211 connected to the through hole 14; the transmission line 32 passes through the through hole 211 and the through hole 14, and is electrically connected to the controller 4.

[0121] The transmission line 32 may be a flexible line, and the transmission line 32 may extend in any direction.

[0122] In some embodiments, the other end of the transmission line 32 extends toward the main housing to facilitate perforation and reduce the length of the transmission line 32 for ease of installation and maintenance.

[0123] The installation position of the terminal block device 2 has at least the following three forms:

[0124] First, as shown in FIG. 1 , at least a portion of the terminal device 2 passes through the through hole 14 .

[0125] In this embodiment, a portion of the terminal block device 2 is located in the junction box 12 , and another portion passes through the through hole 14 and is located in the main box 11 .

[0126] The through hole 211 passes through the terminal device 2 , that is, the through hole 211 communicates with the main box 11 and the junction box 12 .

[0127] By providing the through hole 211 , the transmission line 32 can be electrically connected to the controller 4 without providing the reserved hole 13 on the main box 11 and the junction box 12 , which is simple to operate and flexible to use.

[0128] The transmission line 32 and the via hole 211 can be sealed by injecting sealing glue or plugging with soft rubber.

[0129] The via 211 can be set at any position of the terminal block device 2 , which can be specifically determined according to the installation position of the temperature detection element 31 , as long as it does not affect the locking electrical connection between the terminal block device 2 and the OT terminal.

[0130] Secondly, at least part of the controller 4 passes through the through hole 14, that is, part of the controller 4 and the terminal device 2 are located in the same space. The controller 4 can be directly electrically connected to the terminal device 2 and the temperature detection component 31 without threading, which is convenient for installation.

[0131] Third, the connection wire between the terminal device 2 and the controller 4 passes through the through hole 14 .

[0132] The controller 4 and the terminal block device 2 are located in different spaces. The connection wires between the terminal block device 2 and the controller 4 pass through the through hole 14 to achieve electrical connection between the terminal block device 2 and the controller 4.

[0135] In this embodiment, the temperature detection element 31 is installed on the terminal device 2 in at least four installation positions as follows:

[0140] It is understandable that the transmission line 32 is a flexible line. The transmission line 32 can extend outward from one side of the main box, bypass the insulating enclosure, and then extend toward the reserved hole 13, or pass through the insulating enclosure and then extend toward the reserved hole 13.

[0141] The other end of the transmission line 32 may extend toward the reserved hole 13 to shorten the length of the transmission line 32 , facilitate installation and maintenance, and reduce costs.

[0142] The first mounting countersunk hole 221 can be located at any position of the conductive copper bus 22 as long as it does not affect the locking electrical connection between the conductive copper bus 22 and the terminal.

[0143] The first mounting countersunk hole 221 may be located on a side of the conductive copper bus 22 close to the reserved hole 13 to shorten the transmission distance of the transmission line 32 , improve data accuracy, and facilitate threading.

[0144] The first mounting countersunk hole 221 may be located near the wiring point of the conductive copper bus 22 so that the temperature detection point is close to the wiring point, thereby improving the temperature detection accuracy.

[0149] The conductor base 33 is installed on the conductive copper bus 22 and performs transmission control by collecting the temperature of the conductive copper bus 22, as shown in position B in FIG7 .

[0150] The other end of the transmission line 32 may extend toward the reserved hole 13 to shorten the length of the transmission line 32 and facilitate installation and maintenance.

[0151] The conductor base 33 may be provided with a through hole, and the conductor base 33 may be connected to the conductive copper bus 22 by screws.

[0152] The terminal base 21 is provided with an outwardly protruding insulating enclosure, and a through hole is opened on the insulating enclosure. The other end of the transmission line 32 can pass through the through hole and extend toward the reserved hole 13.

[0156] The fastener 23 can conduct heat, and the transmission control is performed by collecting the temperature of the fastener 23.

[0157] The temperature detection member 31 can be locked onto a small screw reserved on the top of the fastener 23, and the temperature of the terminal connector can be detected through heat conduction of the screw.

[0158] The conductor base 33 may be provided with a through hole, and the fastener 23 passes through the through hole and is connected to the conductive copper bus 22 .

[0159] By installing the conductor base 33 on the fastener 23 , the temperature monitoring point is located at the connection point, thereby increasing the measurement accuracy of the temperature detection element 31 .
