High-voltage chamber access control system

Abstract

The invention discloses a converting station high-voltage chamber access control system which comprises an on-off control circuit, a voice circuit, an exhaust fan power-supply control circuit and a high-voltage access control circuit; wherein one end of the on-off control circuit is connected with a power supply positive pole, the other end of the on-off control circuit is connected with one endsof the voice circuit, the exhaust fan power-supply control circuit and the high-voltage chamber access control circuit; and the other ends of the voice circuit, the exhaust fan power-supply control circuit and the high-voltage chamber access control circuit are respectively connected with power supply negative pole. In the invention, the converting station safety management is enhanced, an accessdoor of a high-voltage chamber is shut off, the access door of the high-voltage chamber is automatically opened after the high-voltage chamber is exhausted for fifteen minutes; voiced safety prompts are provided to people entering the access door of the high-voltage chamber for reminding the people entering the high-voltage chamber of a transformer substation of attending safety, therefore, safety reliability of people entering a danger region of the high-voltage chamber is enhanced.

Description

technical field [0001] The invention relates to a high-voltage room access control system of a substation, which is a voice safety prompt and a control method applied to the entrance of the high-voltage room of the substation. Background technique [0002] At present, with the rapid development of industrial and agricultural production, the rapid improvement of the national economy, the continuous improvement of people's living standards, and the unprecedented development of the power industry, the construction of the national power grid is changing with each passing day. Adopt various technical measures to save land application. In order to save soil and use it, the substation equipment is installed indoors to build an indoor substation. Since the insulation of modern high-voltage electrical equipment uses SF6 gas, SF6 gas produces toxic gas under the action of electric arc, which is harmful to humans. The leakage of SF6 gas is heavy on the ground. For this reason, the re...

AI Technical Summary

Problems solved by technology

At present, the management of leaders, operators, equipment maintenance personnel, and foreign visitors who enter the high-voltage room of the substation is relatively extensive, which is not perfect for the safety of the substation. Therefore, a voice security system for entering the high-voltage room of the substation is invented. Prompt and its automatic control system
