Remotely-operated field-monitoring early-warning device of circuit breaker and implementation method thereof

Abstract

The invention discloses a remotely-operated field-monitoring early-warning device of a circuit breaker and an implementation method thereof, relates to the technical field of power grid running safety, and particularly belongs to a device capable of sending effective prompt information on the spot when a high-voltage room switch is operated remotely and an implementation method thereof. The remotely-operated field-monitoring early-warning device comprises a shell, wherein a single-chip microcomputer, and a power supply module, a communication module, a sound-light alarm module and a voice alarm module which are connected with the single-chip microcomputer respectively are arranged inside the shell. The remotely-operated field-monitoring early-warning device is arranged in a high-voltage equipment room, and accesses a station layer switch in a transformer substation without causing any unsafe factor on other all equipment. Even if the device fails inside, safe running of any other equipment is not influenced, and safety risks caused by the failure of the device do not exist. The remotely-operated field-monitoring early-warning device has the positive effect of increasing the safety coefficient in the field of power grid operation.

Description

technical field [0001] The invention relates to the technical field of power grid operation safety, in particular to a device capable of sending effective prompt information to the site when a high-voltage room switch is remotely operated by remote control and an implementation method thereof. Background technique [0002] Remote operation includes two situations where the dispatching control center remotely operates the switch through the remote machine and the monitoring background machine in the substation. Both of them send the opening and closing instructions to the measurement and control device, and the measurement and control device completes the opening and closing of the circuit breaker. [0003] 5.3.6.4 of the "State Grid Corporation Electricity Safety Regulations" (substation part) requires: before remotely operating the circuit breaker (switch), it is advisable to send a reminder signal to the site to remind the site personnel to stay away from the operating equi...

AI Technical Summary

Problems solved by technology

There are two reasons: one is that the circuit breaker (switch) is operated remotely from a remote location. If there are staff on site patrolling and overhauling, there is no reminder, and the sudden opening or closing of the circuit breaker (switch) will cause damage to the staff. The second is that when the line or the internal fault of the switch causes a trip, after the line inspector finds the fault point and reports to the dispatcher, the dispatcher will force the power transmission according to the situation. When the switch is turned on, the power substation operation and maintenance personnel may be checking the switch cabinet , if a faulty switch explodes, personal injury or death will result
