Abstract

The invention provides a water level monitoring system for a transformer substation cable interlayer. The water level monitoring system comprises a water level detection sensor, a controller, a contactor and a water draining pump, the water level detection sensor is used for detecting water level in the cable interlayer, the controller is provided with a signal input port and a first control signal output port, the signal input port is electrically connected with the water level detection sensor, the contactor is electrically connected with the first control signal output port, and the water draining pump is electrically connected with the contactor. By applying the technical scheme, the water level in the transformer substation cable interlayer is monitored by utilizing the water level detection sensor, and the controller controls the water draining pump to be turned on after the water level reaches warning water level, so that automation in water draining of the transformer substation cable interlayer is realized, and the problem of manpower consumption for draining accumulated water in the cable interlayer in the prior art is solved.

Description

technical field [0001] The invention relates to the field of protection equipment for power supply facilities, in particular to a water level monitoring system for substation cable interlayers. Background technique [0002] In the prior art, it is a common phenomenon in the operation and management of substations to find that water accumulated in the cable interlayer is difficult to discharge during operation and maintenance of the substation. In case of heavy rainfall, it is necessary to dispatch staff to each substation to install water pumps and drainage pipes in the rain when the cable interlayer is blocked or for other reasons, and to carry out manual drainage, which consumes a lot of manpower and material resources, and may even occur. Personnel injury accident. At the same time, if the water in the cable interlayer is not discharged in time, it will cause great safety hazards to the safe and stable operation of the substation. On the one hand, it will make the equipm...
