Monitoring device used for high voltage switch cabinet

Abstract

The invention provides a monitoring device used for a high voltage switch cabinet, and belongs to the field of electric power detection. The monitoring device comprises a mobile telescopic supportingmember, temperature sensors and a power supply module. The mobile telescopic supporting member comprises an external supporting member, an internal supporting member and a base. The internal supporting member is provided with through holes. A supporting frame used for arranging the temperature sensors is fixedly connected in the through hole. The external supporting member is provided with a box which is internally provided with the power supply module, a first control unit and a communication module. A handheld control terminal maintains communication with the first control unit through the communication module. The temperature of the moving and static contacts can be directly detected through the temperature sensors arranged on the mobile telescopic supporting member and transmitted to the handheld control terminal through the first control unit and the communication module, the work personnel can know the temperature of all the moving and static contacts in the high voltage switch cabinet anytime through the handheld control terminal and the heating moving and static contacts can be maintained in time so that the situation of burnout of the high voltage switch cabinet and the fire accident can be avoided.

Description

technical field [0001] The invention belongs to the field of electric power detection, in particular to a monitoring device for a high-voltage switch cabinet. Background technique [0002] High-voltage switchgear is one of the most important electrical hand-held control terminals in substations. During the long-term operation of the hand-held control terminal, the circuit breaker in the switch cabinet and the connecting plug between the switch cabinet and other parts are heated due to excessive contact resistance caused by poor manufacturing, transportation, installation and aging. Since the temperature of these heat-generating parts cannot be monitored , so that timely maintenance is not possible, which eventually leads to burning switchgear and fire accidents. Contents of the invention [0003] In order to solve the shortcomings and deficiencies in the prior art, the present invention provides a temperature sensor to transmit the detected temperature data to the handhel...
