Abstract

The invention discloses a high-reliability cable trench drainage condition detection and control system. The system comprises a remote terminal control module, an alternating current detection module,a switching power supply, a control circuit and a liquid level switch; the anode of the control circuit is connected to the anode of the switching power supply; the cathode of the control circuit isconnected to the cathode of the switching power supply, the input end of the remote terminal control module is connected with the output end of the control circuit, the sampling end of the alternatingcurrent detection module is connected with the alternating current input of a water pump main circuit, and the output contact of the alternating current detection module is connected to the control circuit. The remote terminal control module, the alternating current detection module, the switching power supply and the control circuit are utilized to form the cable trench drainage pump operation state detection and control system, water level detection and remote alarm and control are realized by combining the liquid level switch, and effective monitoring of the drainage condition of a transformer substation is realized.

Description

technical field [0001] The invention relates to the technical field of detection and control, and more particularly, to a highly reliable cable trench drainage status detection and control system. Background technique [0002] During heavy rains, some substations and cable trenches in district and county bureau power distribution rooms will accumulate water due to flooding. The operation and maintenance personnel cannot timely and effectively grasp the operation status of the automatic water pump. Whenever it rains, the operation and maintenance personnel need to go to the site to check the operation status of the water pump in person in order to ensure that there is no water accumulation in the cable trench. [0003] 1. At present, the alarm information of automatic drainage products on the market is single. The maintenance personnel cannot know the fault situation in detail [0004] 2. The upper master switch of the automatic drainage device has a trip phenomenon. Once ...
