Description

Technical Field

[0001] This utility model relates to the technical field of relay protection shorting wire devices, and more specifically, to relay protection shorting wire devices. Background Technology

[0002] The relay protection shorting device is a special tool used for temporarily shorting secondary circuits (such as current circuits, voltage circuits, or control circuits) during the commissioning, maintenance, or testing of relay protection in power systems. Its core function is to ensure the safety of maintenance operations and prevent protection malfunctions or equipment damage.

[0003] Currently, in the secondary circuit of relay protection, opening the secondary side of the current transformer is strictly prohibited as it can easily generate high voltage, endangering personal and equipment safety. Conversely, short-circuiting the secondary side of the voltage transformer is strictly prohibited as it can lead to overcurrent and burn out equipment. Therefore, a relay protection short-circuit device is provided that allows temporary short-circuiting of relevant circuits during maintenance and verification of the secondary circuit. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a relay protection shorting wire device, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a relay protection shorting wire device, including a base, on which a detection component is provided;

[0006] The detection component includes a processor disposed within a base, the processor being embedded within the base, and a plurality of detection heads disposed on the top of the base, each of the detection heads having a protective cover on its top.

[0007] Each of the multiple protective covers is equipped with an overcurrent protector, and each overcurrent protector has a conductive element at its top. A light-emitting diode is provided on one side of the inner wall of the protective cover, and the top of the light-emitting diode extends to the light-emitting diode. Several copper busbars are provided on the side of the conductive element away from the light-emitting diode, and each copper busbar has a pin at its bottom. The pin is inserted into the detection head. The copper busbars are fixed to the overcurrent protector by soldering, and the overcurrent protector is embedded in the bottom of the inner cavity of the protective cover and is snapped into the protective cover.

[0008] Optionally, in a possible implementation, one end of the detection head is provided with a terminal block, the terminal block is mounted on the base by bolts, the terminal block is provided with a plurality of interfaces, and each interface is located at one end of the corresponding detection head. Protective plates are provided at both ends of the base, and each protective plate is provided with a slot.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] This utility model uses a protective cover to physically isolate conductive components such as overcurrent protectors and copper busbars. Combined with the protective plates at both ends of the base, it can effectively prevent operators from directly contacting live parts and reduce the risk of electric shock. The overcurrent protector is connected in series in the circuit. When an abnormal overcurrent occurs, it can quickly cut off the circuit to prevent excessive current from burning out the equipment or damaging the device's own components. This solves the safety hazards that traditional short-circuit tools may cause due to overcurrent.

[0011] The LED inside the protective cover is linked with the conductive components. When the device successfully short-circuits the target circuit and the circuit is conductive, the LED lights up, providing intuitive feedback. If the short-circuit is loose or the circuit is broken, the LED does not light up. Operators can quickly identify the abnormality and avoid risks such as open circuit on the secondary side of the current transformer due to poor contact. This solves the problem that traditional tools are difficult to quickly confirm the short-circuit status. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figures 1-4 The relay protection shorting wire device shown uses a detection component on the base 1 and a protective cover 4 to physically isolate conductive components such as the overcurrent protector 5 and copper busbar 8. Combined with the protective plates 12 at both ends of the base 1, it can effectively prevent operators from directly contacting live parts and reduce the risk of electric shock. The overcurrent protector 5 is connected in series in the circuit. When an abnormal overcurrent occurs, it can quickly cut off the circuit to prevent excessive current from burning out the equipment or damaging the device's own components. It solves the safety hazards that traditional shorting tools may cause due to overcurrent. The specific structural settings of the components are as follows.

[0020] The detection assembly includes a processor 2 disposed within a base 1. The processor 2 is embedded within the base 1. Several detection heads 3 are disposed on the top of the base 1, and each detection head 3 is provided with a protective cover 4 on its top. Overcurrent protectors 5 are disposed within the multiple protective covers 4, and a conductive element 6 is disposed on the top of each overcurrent protector 5. A light-emitting diode 7 is disposed on one side of the inner wall of the protective cover 4, with the top of the light-emitting diode 7 extending to the top of the light-emitting diode 7. Several copper busbars 8 are disposed on the side of the conductive element 6 away from the light-emitting diode 7, and a pin 9 is disposed at the bottom of each copper busbar 8. The pin 9 is inserted into the detection head 3. The copper busbar 8 and the overcurrent protector 5 are fixed by soldering, and the overcurrent protector 5 is embedded in the bottom of the inner cavity of the protective cover 4 and is snapped into the protective cover 4.

[0021] One end of the detection head 3 is provided with a terminal block 10, which is mounted on the base 1 by bolts. The terminal block 10 has several interfaces 11, and each interface 11 is located at one end of the corresponding detection head 3. Protective plates 12 are provided at both ends of the base 1, and each protective plate 12 has a slot.

[0022] The specific working principle is as follows: the device is connected to the target secondary circuit, such as the current circuit or voltage circuit, through the terminal block 10 on the base 1. The interface 11 on the terminal block 10 is connected to the secondary circuit wires to ensure that the current is introduced into the device from the external circuit. The current is transmitted to the detection head 3 through the interface 11. The pin 9 at the top of the detection head 3 is inserted into the bottom of the copper busbar 8, so that the current is further conducted to the overcurrent protector 5 through the copper busbar 8. The copper busbar 8 and the overcurrent protector 5 are fixed by soldering to ensure the reliability of the conduction.

[0023] The overcurrent protector 5 is embedded in the protective cover 4 and connected in series in the current conduction path. When an abnormal overcurrent occurs in the circuit, such as a short circuit current caused by accidentally short-circuiting the secondary side of the voltage transformer, the overcurrent protector 5 will act quickly, such as melting or disconnecting, to cut off the current conduction path and prevent excessive current from damaging internal components of the device, such as the copper busbar 8, the detection head 3, or external secondary equipment, such as the current transformer and voltage transformer, thus achieving active safety protection.

[0024] The protective cover 4 provides physical isolation for core conductive components such as the overcurrent protector 5 and copper busbar 8, preventing operators from directly contacting live parts. At the same time, the protective plates 12 at both ends of the base 1 enhance the overall structural stability through slots, further improving operational safety. The LED 7 on the inner wall of the protective cover 4 forms a circuit with the conductive component 6. After receiving the current signal transmitted by the overcurrent protector 5, the conductive component 6 outputs a weak current to the LED 7. When the device successfully short-circuits the target circuit and the circuit is conductive, the LED 7 lights up, providing a direct feedback that the short circuit is effective. If the short circuit is loose or the circuit is broken, the LED will not light up, allowing operators to quickly identify the abnormality and avoid risks such as open circuits on the secondary side of the current transformer due to poor contact.

[0025] The processor 2 embedded in the base 1 serves as the control core, collecting real-time status signals from the detection head 3 and the overcurrent protector 5, such as current magnitude and overcurrent action signals. When the overcurrent protector 5 activates or an abnormality occurs in the circuit, the processor 2 can use internal logic to determine and coordinate the state changes of the LED 7, such as flashing an alarm or recording abnormal information, to assist operators in quickly locating the fault and improving maintenance efficiency.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
