Description
Technical Field
The utility model relates to the technical field of circuit breakers, in particular to a terminal strip short-circuit plug.
Background
The circuit breaker characteristic test is one of the contents in the routine test work of the transformer substation, and the data obtained by the characteristic test can be used as an important basis for judging the performance and the working condition of the circuit breaker.
Under the condition of power failure, a breaker characteristic test instrument is used for testing, the test instrument is connected with the breaker through a switching-on and switching-off trigger line, and the breaker is required to be switched on and off so as to acquire test data. The direct current sent by the test instrument is transmitted to the secondary circuit of the breaker for switching on and off through the switching-on and switching-off trigger line, so that the breaker is switched on and off.
Because the 220kV circuit breaker adopts a single-phase action mode, the positive pole of the switching-on and switching-off secondary circuit line of the 220kV circuit breaker is divided into ABC three phases, and after the secondary power supply is disconnected, three secondary circuit lines of the switching-on and switching-off positive pole are detached by maintenance personnel at ordinary times, a wire clamp of the switching-on and switching-off positive pole trigger wire is clamped on the ABC three-phase positive pole secondary circuit line, and a wire clamp of the switching-on positive pole trigger wire is clamped on the ABC three-phase positive pole secondary circuit line.
The clamp is difficult to clamp three secondary loop wires, multiple adjustment is needed, and the condition that one phase or two phases of secondary loop wires are in virtual connection often occurs, and the three phases cannot be completely switched on or off, so that the test fails, and the characteristic test is needed to be carried out again after the clamp is adjusted. If the situation that the secondary wire cannot be disassembled due to ageing of the terminal strip is encountered, the three-phase terminal strip is required to be manually shorted, the three-phase terminal strip is very difficult to be manually shorted, the virtual connection is easy, and time and labor are wasted.
Therefore, how to design a terminal strip shorting device suitable for the circuit breaker characteristic test is a technical problem that needs to be solved currently by those skilled in the art.

Wherein shorting bar base 100 serves as a support member providing a mounting base for terminal bar plug 200. The material of the shorting bar base 100 is a conductive material, and may be copper or aluminum, and the specific material is not limited herein, so long as the conductive requirement can be met, and the specific size of the shorting bar base 100 is specifically determined according to the actual situation.
It should be noted that the circuit breaker characteristic test is one of the contents in the routine test work of the transformer substation, and the data obtained by the characteristic test can be used as an important basis for judging the performance and the working condition of the circuit breaker.
Under the condition of power failure, a breaker characteristic test instrument is used for testing, the test instrument is connected with the breaker through a switching-on and switching-off trigger line, and the breaker is required to be switched on and off so as to acquire test data.

Because the 220kV circuit breaker adopts a single-phase action mode, the opening and closing positive pole secondary circuit line of the 220kV circuit breaker is divided into ABC three phases, and when the circuit breaker characteristic test is carried out, only the ABC three-phase positive pole terminal strip is required to be short-circuited. For convenience of explanation, the three-phase positive terminal block of the circuit breaker ABC will be hereinafter referred to as a circuit breaker terminal block.
In order to meet the shorting requirement of the breaker terminal block, the number of the terminal block plugs 200 is three, and the terminal block plugs correspond to the three-phase terminal block of the breaker ABC and are used for being plugged on the breaker terminal block. The terminal strip plugs 200 are disposed on the shorting strip base 100 and are disposed along the length direction of the shorting strip base 100, i.e. three terminal strip plugs 200 are disposed in a straight line.
The utility model provides a terminal strip short-circuit plug which is used for a circuit breaker characteristic test and comprises a short-circuit strip base 100 and terminal strip plugs 200, wherein the number of the terminal strip plugs 200 is three, the terminal strip plugs are arranged on the short-circuit strip base 100 and are arranged along the length direction of the terminal strip plugs 200, and the terminal strip plugs 200 are used for being inserted into circuit breaker terminal strips. When the circuit breaker is required to be subjected to characteristic test, the terminal strip plug 200 is inserted into the terminal strip of the circuit breaker, the wire clamp of the opening and closing positive trigger wire is clamped to any conductive part of the terminal strip short-circuit plug, and after the negative electrode wiring and the measuring wire are connected, a circuit breaker characteristic test instrument is started for test.

In order to enable the distance between the terminal strip plugs 200 to be adjusted according to the actual situation, in a specific embodiment of the present utility model, each terminal strip plug 200 is slidably engaged with the shorting strip base 100. When the distance between two adjacent terminal strip plugs 200 needs to be adjusted, the terminal strip plug 200 which needs to be adjusted is moved. The material of the terminal strip plug 200 may be a conductive material, copper material, or other conductive materials. The terminal strip plug 200 and the shorting strip base 100 are in sliding fit in various manners, and sliding fit can be realized by arranging a sliding groove or by directly contacting the terminal strip plug 200 with the surface of the shorting strip base 100.
