Intelligent control system of draining pumps in transformer substation water collecting well

Abstract

The invention discloses an intelligent control system of draining pumps in a transformer substation water collecting well. The intelligent control system comprises a plurality of draining pumps arranged in the water collecting well, a water level sensor, a current operation detecting device, a water pump control electrical cabinet, a water pump intelligent controller, an RCU intelligent terminal,a master station centralized control processing device and a transformer substation comprehensive monitoring center, wherein the draining pumps are connected with the water pump control electrical cabinet; each of the water level sensor, the current operation detecting device and the water pump control electrical cabinet is connected with the water pump intelligent controller; and the water pump intelligent controller, the RCU intelligent terminal, the master station centralized control processing device and the transformer substation comprehensive monitoring center are sequentially connected.The intelligent control system can avoid the phenomenon that the water pump refuses to start or is frequently started by mistake due to malfunction of a floating ball, the water level monitoring means is more stable and reliable, remote visual management of the water pump control can be realized, the reported data can be verified, and operation is visualized; and the current operation detecting device monitors the power supply current information of the water pump, can judge the operating(start-stop) state of the water pump and timely finds the failure state, so that precise maintaining datais provided for a maintaining staff, the source is saved, and the effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of substation management and control equipment, in particular to an intelligent control system for a water collection well drainage pump of a substation. Background technique [0002] The low-lying sites of substations and power cable tunnels are prone to flooding risks during the rainy season, which can easily cause insulation degradation and even short-circuit and ground faults. In order to prevent water from entering the site, it is necessary to install submersible drainage pumps in the water collection wells at the most unfavorable points such as the cable layer of the substation, the fire pool, and the power cable tunnel for drainage to ensure the safe operation of power equipment. [0003] At present, domestic general substations and power cable tunnel drainage pump control systems mostly use on-site water collection wells to add floating balls. figure 1 , when the water level in the collection well e...

AI Technical Summary

Problems solved by technology

The water collection wells of substations are generally designed in the corners of the station, but they are far away from the main control room of the substation and the personnel on duty. Most of the time when the water collection wells need to be drained is severe rain. Walking between electrical equipment brings risks to personal safety, and at this time, the power grid system is often in a period of frequent operation failures, requiring substation duty personnel to pay close attention to the operation of the power grid and cooperate with power grid operations in a timely manner, and cannot withdraw to observe storage If the water level of the pool is poor, it may cause the drainage system of the reservoir to be turned on and off in time, and then cause the substation cable layer or the factory area to overflow, which will bring great safety hazards to the cables and electrical equipment in the station.
