Fault warning and wastewater recycling system for drainage device of underground substation

Abstract

The invention discloses a fault warning and wastewater recycling system for a drainage device of an underground substation. The fault warning and wastewater recycling system comprises a water level status detection and warning device, a drainage pump, irrigation troughs, a drainage trough, lawn planting baskets and filter nets. The water level status detection and warning device is located at thebottom of the underground substation. Grooves for placing the lawn planting baskets are arranged in the top of the underground substation. Multiple columns of lawn planting baskets are placed in parallel in the grooves arranged in the top of the underground substation. The gaps between the adjacent lawn planting baskets and between the lawn planting baskets and the grooves form the irrigation troughs. The drainage trough is arranged at the edge of the grooves arranged in the top of the underground substation. The fault warning and wastewater recycling system provides real-time detection of water accumulation and water level for the unmanned underground substations of State Grid Corporation, and provides double detection insurance. Moreover, the fault warning and wastewater recycling systemhas the characteristics of safety, reliability, simple operation and accurate data, and ensures the safe and stable operation of underground equipment and greatly improves the reliability of the power grid.

Description

technical field [0001] The invention relates to drainage and waste water utilization systems, and more specifically, to a fault warning and waste water recycling system for underground substation drainage devices. Background technique [0002] As a building facility for power transmission and distribution, substations mostly adopt the unattended mode, and it is very important to pay attention to its drainage function, especially for substations built on low terrain, its drainage function is particularly important. At present, underground substations mostly use two methods for drainage: 1. Set up drainage ditches and drain pipes; 2. Install water pumps for extraction, and control the start and stop of water pumps through water level detection devices. This type of substation has the following problems: 1. The setting of the drainage ditch needs to bypass the cable trench, and the cable trench does not have drainage function, and groundwater and surface water may enter the cab...

AI Technical Summary

Problems solved by technology

This type of substation has the following problems: 1. The setting of the drainage ditch needs to bypass the cable trench, and the cable trench does not have drainage function, and groundwater and surface water may enter the cable trench to soak the cables; 2. The current automatic drainage in the unattended substation The system is not equipped with status detection and early warning systems, and failures cannot be detected and dealt with in a timely manner. This is also one of the reasons for problems in the power system in domestic heavy rainstorm areas in recent years; 3. The waste water discharged from the substation is not used.
