Abstract

The invention discloses a circuit breaker anti-trip test device for solving the problems that circuit breaker anti-trip test work is too tedious, and time consuming is too long in the prior art. The device comprises that a first microprocessor module is connected with a first oscillation circuit, a first reset circuit, a first digital display module, a timing switch, a first open-in binding post and a power supply module; a second microprocessor module is connected with a second oscillation circuit, a second reset circuit, a second digital display module, the timing switch, a second open-in binding post and the power supply module; and the timing switch is connected to an open-out stem node. The circuit breaker anti-trip test device has the beneficial effects that it is suitable for all circuit breakers, small in size, convenient to carry, easy to operate and has enough voltage resistance; and after using the circuit breaker anti-trip test device, the working duration of the circuit breaker anti-trip test is shortened from previous40 minutes to 10 minutes, the labor intensity of workers is greatly reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a circuit breaker anti-jump test device. Background technique [0002] In the operation of the substation, there are often multiple "jumps" of the circuit breaker, that is, the contact of the control switch or the contact of the automatic device is stuck or stuck when the circuit breaker is manually or automatically reclosed. The protection device operates to trip the circuit breaker. After the trip, it is closed again due to the above reasons, and the fault is permanent. The circuit breaker will trip again, then close again and trip again. This "jump-close" phenomenon occurs repeatedly. Called "jumping". When the "jumping" phenomenon occurs in the circuit breaker, the power system will be impacted by the short-circuit current for many times, which may cause the shock of the power system. The condition was very harsh and the damage to it was great. [0003] At present,...
