The automatic warning device adopts the following technical proposal: a closed container of the automatic warning device for detecting barometric pressure is internally provided with a sensor module which is connected with a host computer in a wireless way. Compared with the prior art, the automatic warning device combines electronic detecting barometric pressure and wireless transmission to be used for the detection and alarm of the closed container of equipment for power transmission and distribution, so as to realize remote monitoring and automatic alarm by receiving through the host computer and lead the facilities maintainer to check and repair in time, furthermore, the equipment is not operated under the unsafe condition and safety misadventure can not be caused.
Description
Technical field
The utility model relates to the barometric surveying and the panalarm of the airtight arc-control device of a kind of equipment for power transmission and distribution, particularly a kind of equipment for power transmission and distribution.
Background technology
In the power transmission and distribution industry, in the complete controller switching equipment of the 10-24KV system, often use inert gas, sulfur hexafluoride SF6 or vacuum arc-extinguishing device guarantee the normal use of controller switching equipment, as SF6 isolating switch or vacuum circuit breaker.Whether the gaseous tension in the closed container of arc-control device maintains in the trouble free service numerical range of regulation, very important to the safe handling of equipment for power transmission and distribution.For 10KV electric pressure and above equipment, if the air pressure in the closed container has been lower than safety value, might cause equipment explosion, injure operating personnel.Prior art uses pointer rain glass to measure closed container interior SF6 pressure or vacuum tightness, closed container is provided with the rain glass joint, connect rain glass by the rain glass joint, the deficiency that this structure exists is: increased source of leaks on the closed container, the SF6 gas that leaks can pollute surrounding environment, gaseous tension in the closed container exceeds safety value, has shortened the mission life of arc-control device.
Summary of the invention:
The purpose of this utility model provides a kind of air pressure and detects autoalarm, and the technical matters that solve is no Leak Detection air pressure and reports to the police.
The utility model is by the following technical solutions: a kind of air pressure detects autoalarm, and described air pressure detects in the closed container of autoalarm and is provided with sensor assembly, sensor assembly and main frame wireless connections.
Sensor assembly of the present utility model is provided with baroceptor, and baroceptor is connected with the emitting antenna of sensor assembly through transmitter module.
Sensor assembly of the present utility model is provided with the electric battery into the baroceptor power supply.
Main frame of the present utility model is provided with main control chip, and main control chip is connected with the receiving antenna of main frame through demodulation module, and main control chip also connects light-emitting diode display and control antenna respectively.
Main frame of the present utility model is provided with the electric battery into the main control chip power supply.
Main control chip of the present utility model is provided with operation push-button.
Main control chip of the present utility model outputs control signals to relay and remote transmitting device.
Relay of the present utility model connects warning light or hummer.
The utility model compared with prior art, detection of electrons air pressure and wireless transmission are combined, the closed container that is used for equipment for power transmission and distribution detects and warning, receive by main frame, realize remote monitoring, report to the police automatically, the plant maintenance personnel are in time overhauled, can't cause security incident in the unsafe condition operate equipment.
