Insulating operating rod

Abstract

The invention discloses an insulating operating rod which comprises an operating rod body, a current detection module and an alarm module which are fixedly arranged on the operating rod body, and a processing module which is connected with the current detection module and the alarm module. The processing module controls the alarm module to send out an alarm signal when the current value detected by the current detection module exceeds a preset value. When an electric power worker holds the insulating operating rod by hand to execute the power failure switching operation by mistake, a high-voltage isolation knife switch is disconnected firstly. Since a high-voltage circuit breaker is not disconnected, the current detection module detects a current signal which flows through the high-voltageisolation knife switch and transmits the current signal to the processing module. The processing module controls the alarm module to emit an alarm signal. The operating rod body can be bent and locked by arranging an execution mechanism, so that an electric power worker is reminded of an operation error and cannot continue to execute an error operation. Therefore, the insulating operating rod caneffectively prevent electric power workers from mistakenly executing switching operation. The safety coefficient of an electric power construction site is improved.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an insulating operating rod. Background technique [0002] In power production work, switching electrical equipment is a basic job for electric workers, and insulated operating rods are required to carry out this task. Although the construction of insulating operating rods is simple, it is very important for operating transformers. The circuit breaker switch and isolating knife switch on the rack are very useful, instead of electric workers climbing onto the transformer stand, they only need to use the insulating operating rod to pull lightly to complete the power failure switching operation. [0003] The correct operation sequence for power outage switching is to first disconnect the high-voltage circuit breaker and then open the high-voltage isolation switch. During the operation, the staff must strictly follow the relevant requirements to avoid unnecessary dangerous...

AI Technical Summary

Problems solved by technology

However, if the operation sequence is wrong, if the high-voltage isolation switch is opened first and then the high-voltage circuit breaker is disconnected, a large number of arcs will be generated, which will not only cause damage to the equipment, but also seriously threaten the safety of the staff on site.
