Active environment protection device for ring main unit

Abstract

An active environment protection device for a ring main unit is composed of an information acquisition unit, an information processing unit, an alarm unit, a control unit, a wireless communication unit, a power supply unit and a background server, the information acquisition unit is connected with the information processing unit, the information processing unit is connected with the alarm unit, the control unit and the wireless communication unit, and the wireless communication unit is connected with the background server. The information acquisition unit is used for acquiring temperature signals by mounting a plurality of temperature sensors at a bus joint, a switch cabinet contact and an outgoing cable head. SF6 gas in the cabinet body, water immersion in the cabinet body, condensation in the cabinet body and insulation resistance in the cabinet body are sampled and monitored. The information processing unit includes a microprocessor circuit and a memory circuit. The control unit comprises a fan control circuit, a dehumidifier control circuit and a heater control circuit. The device has the beneficial effects that the operation condition of the ring main unit can be fully mastered, and the normal operation of the ring main unit is ensured.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to an active environmental protection device for a ring network cabinet. Background technique [0002] The ring main unit is a very critical equipment in the distribution network installation, which undertakes the heavy responsibility of putting some power lines into operation or cutting them out. It is related to the operation level, safety degree and power supply service quality of the distribution network. Once the ring main unit is especially It is the failure of its high-voltage switchgear, which will first cause damage to related power equipment and lines, and then cause large-scale power outages and other power supply accidents that affect the normal production and life of the people. [0003] At present, the fault types of the ring network cabinet mainly include the following common faults: [0004] Insulation discharge fault: The main reason for the discharge of the sw...

AI Technical Summary

Problems solved by technology

[0005] Overheating fault: The closed switch cabinet cannot be opened during operation, so it is difficult to measure the actual temperature of the contacts in the cabinet. If the contact overheating defect cannot be found and dealt with in time, it will seriously threaten the safety of electric power production
