Transformer substation protection chamber cable layer water inflow damp fire and cable discharge alarm system

Abstract

The invention discloses a transformer substation protection chamber cable layer water inflow damp fire and cable discharge alarm system. The system comprises a background computer, a switch, a detection box and a field detection box. And a PLC modem, a water immersion monitoring sensor, a temperature sensor, a humidity sensor, a smoke sensor, an arc light protection module and a monitoring moduleare arranged in the detection box. When the detection box is far away from the background computer and the switch, the switch with an optical port can be selected or an optical cable, a tail fiber andthe like are adopted for direct connection; when the investment is limited, a common electro-optical port switch or a photoelectric converter is adopted for switching; when distance exchange is carried out, network cable arrangement can be directly adopted; the system comprises water immersion monitoring, temperature and humidity detection, fire detection and arc light protection, sensor data aretransmitted to a monitoring system of a main control room, faults are found in time and processed as soon as possible, all related detection boxes can be monitored in a unified mode, a protection chamber cable layer can be monitored, and effective measures can be taken.

Description

technical field [0001] The invention belongs to the technical field of substation accident alarm systems, and in particular relates to a substation protection cell cable layer water-damaged fire and cable discharge alarm system. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in the power plant is a step-up substation. Its function is to boost the electric energy generated by the generator and feed it to the high-voltage power grid. The electrical equipment in the substation is divided into primary equipment and secondary equipment. Primary equipment refers to direct production and transmission. , Distribution and use of electrical energy equipment, mainly including transformers, high-voltage circuit breakers, isolating switches, busbars, lightning arresters, capacitors, reactors, etc.; secondary equipment in substations refers to the measurem...

AI Technical Summary

Problems solved by technology

The cable layer is in the lower layer of the protection chamber, so it is difficult to monitor its status. Due to the influence of moisture and temperature, it is easy for the cable to be damp, the temperature is too high, or even accidents such as water immersion, fire, arc discharge, etc., due to the slow detection time , easy to cause major accidents, the existing protection cell cable layer is generally only equipped with smoke alarms connected to the fire alarm system, lack of other aspects of monitoring, for this reason we propose substation protection cell cable layer water ingress fire and cable Discharge alarm system to solve the problems in the prior art
