Movable circuit breaker characteristic test wiring terminal block device and use method thereof

Abstract

The invention belongs to the field of circuit breaker maintenance auxiliary instruments, and particularly relates to a movable circuit breaker characteristic test wiring terminal strip device and a use method. The body is provided with two strip-shaped through holes, and the plurality of plugging terminals are sequentially plugged in the strip-shaped through holes and can be temporarily fixed in the strip-shaped through holes or move along the strip-shaped through holes. The plugging terminals are detachably installed in the strip-shaped through holes, and the positions and the number of the strip-shaped through holes correspond to those of tested wiring terminal strips. And a bracket for fixing is arranged on the body. When a circuit breaker characteristic test is carried out, the body isfixed on an original terminal strip, the plugging terminals can move, the plugging terminals are screwed in and tightly attached to the original terminal strip, then the test joints are inserted intoterminals of the test terminal strip, and reliable connection between the test lines and the original terminal strip is achieved. Test joints can be adjusted only by adjusting the plug terminals in different test items, the disassembly and assembly are convenient, the original terminal strip is not damaged, the terminals are in good butt joint, and the operation space is saved; the plugging terminals can slide, the matching degree is high, and the operation is simple.

Description

Technical field: [0001] The invention belongs to the field of circuit breaker maintenance auxiliary equipment, and relates to a movable circuit breaker characteristic test terminal block device and a use method. Background technique: [0002] During the operation characteristic test of the circuit breaker maintenance test, the test wiring is cumbersome due to the different types of terminal blocks of the control cabinet of each type of circuit breaker, especially when the closing and opening test requires the cooperation of multiple people, which brings difficulties to the maintenance work ;Different test items also need to change the wiring frequently, often due to the mismatch between the test line connector and the terminal block, poor contact affects the test and reduces work efficiency. Invention content: [0003] Purpose of the invention: [0004] The invention proposes a movable circuit breaker characteristic test wiring terminal block, the purpose of which is to s...
