Abstract
The invention relates to a backup power source for a coal mine electronic device, which is provided with a charging adapter, a 24V DC storage battery, a voltage surge resistance protective circuit and a coal mine electronic device; the charging adapter is connected with the voltage surge resistance protective circuit in series; the voltage surge resistance protective circuit is connected with the 24V DC storage battery, a polarity protection and voltage regulator circuit in series; and the polarity protection and voltage regulator circuit is connected with the coal mine electronic device in series. The backup power source for a coal mine electronic device can keep the electronic device to work normally on the premise of maintaining the power-cut state of the comprehensive protective device, thereby greatly enhancing the operation stability of the coal mine electronic device, and providing a powerful technical support for safe high-efficiency production of the entire coal mine.
Description
Technical field
The present invention relates to a kind of supply unit, be specifically related to a kind of colliery electronic equipment back-up source.
Background technology
The stable operation of pit gear is very great to safety of coal mines, High-efficient Production meaning.Underground equipment has mostly been used complex protection device, can effectively improve the fail safe and the reliability of equipment operation; When equipment breaks down, also made things convenient for maintenance.In a single day the electric power system of down-hole has a power failure, and comprehensive protector has also just lost power supply, has stopped operation, brings great hidden danger for the safety in production in colliery.This shows, keep that complex protection device continues, the meaning of reliability service is very great.
Ground generally all is equipped with DC power supply with comprehensive insurance system, and purpose is when the external power supply outage of complex protection device, keeps the normal operation of whole relaying protection system; And the comprehensive insurance system in down-hole does not have similar stand-by power supply, in case the external power supply decompression, all complex protection devices are all with out of service.Not only make underground equipment lose protection, the investigation maintenance of returning fault brings great inconvenience.
Summary of the invention
In order to solve some unfavorable problems that existing underground power supply system exists, the invention provides a kind of colliery electronic equipment back-up source, this colliery electronic equipment back-up source can continue to keep complex protection device under situation about having a power failure, continue to keep the electronic equipment operate as normal, greatly improved the stability of colliery electronics operation, powerful technical support is provided for safety, the High-efficient Production in whole colliery.
The technical solution adopted for the present invention to solve the technical problems is: this colliery electronic equipment back-up source comprises charging adapter, anti-voltge surge protective circuit, 24V direct-flow storage battery, polarity protection and voltage stabilizing circuit, colliery electronic equipment, and this colliery electronic equipment back-up source is provided with a charging adapter, 24V direct-flow storage battery, anti-voltge surge protective circuit and colliery electronic equipment.
Described charging adapter and anti-voltge surge protective circuit are in series, and anti-voltge surge protective circuit and 24V direct-flow storage battery, polarity protection and voltage stabilizing circuit are in series, and described polarity protection and voltage stabilizing circuit and colliery electronic equipment are in series.
The invention has the beneficial effects as follows: this colliery electronic equipment back-up source can continue to keep complex protection device under situation about having a power failure, continue to keep the electronic equipment operate as normal, greatly improved the stability of colliery electronics operation, powerful technical support is provided for safety, the High-efficient Production in whole colliery.
