Embodiment Construction

[0022] Embodiment of maintenance system for live maintenance switchgear

[0023] The object of the maintenance system of the live maintenance switchgear provided by this embodiment is the switchgear, specifically the operating mechanism of the checked switchgear. When the operating mechanism of the checked switchgear fails, use the maintenance system Repair and replace.

[0024] The overhaul system includes an electrical locking unit and a secondary signal comprehensive processing unit. Among them, the electrical locking unit is used to simulate the normal operating conditions of the inspected switchgear when overhauling the operating mechanism of the inspected switchgear, specifically: the electrical locking unit monitors the SF 6 The internal and external locking information such as the gas state and the position state of the switchgear can also set the energy storage state of the switchgear to realize the normal operation condition simulation of the switchgear. In this wa...

Abstract

The invention relates to a maintenance system and method capable of maintaining switch equipment in a hot-line manner. The maintenance system is characterized in that a normal operating condition of the maintained switch equipment is simulated by using an electrical locking unit when maintenance is performed on the maintained switch equipment so as to prevent the protection misoperation of an electric power system. In addition, when the electric power system breaks down and needs protection in the maintenance process, the maintained switch equipment is maintained and cannot perform a protection operation, a secondary signal comprehensive processing unit sends a corresponding signal to protection measurement and control equipment in the electric power system, and the protection measurementand control equipment performs a protection operation by using other switch equipment such as higher-level protection so as to achieve backup protection for the electric power system. Therefore, the system does not cause misoperation for the maintained switch equipment in the maintenance process, so that fault detection and emergency maintenance under a hot-line condition can be achieved through the system, and thus the trouble of going through equipment power failure procedures are saved. The maintenance system can reduce the planned and non-planned power failure time especially for a high-voltage electric power system.

Description

technical field [0001] The invention relates to a maintenance system and method for live maintenance switchgear. Background technique [0002] At present, in the power system, the live detection is widely used in the power system, which can find the latent fault of the equipment, but because it cannot solve the misoperation of the switch equipment during the live maintenance process, ensure the safety of personnel and equipment, and the stable operation of the equipment under the condition of mechanical failure, etc. The problem, whether it is post-mortem / troubleshooting, preventive maintenance, condition-based maintenance, or reliability inspection, is that switchgear must be troubleshooted in the event of a power system outage. When a power outage is required to repair the equipment, it is necessary to go through the equipment power outage procedure. The process is cumbersome, and it will also increase the unplanned power outage time, reduce the operation and maintenance a...
