Portable analog circuit breaker

Abstract

The invention discloses a portable analog circuit breaker which comprises a shell. A remote control public terminal J1, a remote control opening terminal J2, a remote control closing terminal J3, an opening signal terminal J4, a remote signaling public terminal J5, a closing signal terminal J6, a first button SW1, a second button SW2, an opening prompting lamp L1, a closing prompting lamp L2, an opening signal lamp L3 and a closing signal lamp L4 are arranged outside the shell. And a control power supply, an opening relay K1, a closing relay K2, an opening position relay K3 and a closing position relay K4 are arranged in the shell. According to the invention, transformer substation remote control logic verification can be completed under the condition of not actually remotely controlling the split-and-one operation equipment, so that the risk of mistakenly remotely controlling the operation equipment is avoided; in the testing process, only one remote signaling public end is detached to be connected into the simulation circuit breaker, wiring simulation setting does not need to be detached, the number of times of wiring detachment is only one, and the risks of wiring recovery errors and wrong short wires are avoided.

Description

technical field [0001] The invention relates to the technical field of substation analog measurement and control, in particular to a portable analog circuit breaker. Background technique [0002] With the promotion of unattended substations, the requirements for dispatching automation are getting higher and higher. The dispatching end needs to realize the remote control of the equipment functions in the station. First verify the correctness of the logic of the remote control function. Therefore, an important acceptance link of the automation professional before the substation equipment is put into operation is to carry out remote control logic verification, such as the remote control function of circuit breakers, isolation switches, and transformer gears. In order to prevent false remote control of intervals or equipment, remote control function verification must be carried out. [0003] Remote control test The remote control test of circuit breaker and isolating switch ca...

Problems solved by technology

[0005] (1) High safety risk: every time the remote control is changed, it needs to be disconnected and short-circuited to reset again. Frequent disconnection and connection of live wires will easily lead to secondary miswiring and remote control of other equipment, increasing safety risks;

[0006] (2) Time-consuming and labor-intensive: there are many operation steps, resulting in long time-consuming, and three people are required to operate at the same time, the success rate is not high
