Recently，Employees passing by the underground central substation of Hanjiawan Coal Company always stop to take a look，Can’t help but sigh，“The environment here is really changed，Keep it as tidy as your home。”
After two months of careful "dressing up"，Days ago，The upgrade and renovation of the underground central substation of Hanjiawan Coal Company was successfully completed，Standing under the 100-meter well with a completely new look，Becomes a demonstration project for the company’s safety production standardization construction。
This upgrade is not only an improvement in “appearance”，There is also the shaping of “connotation”。Without expanding the chamber，By optimizing equipment row spacing，Enhanced on-site spatiality；Built-in high-definition video capture device，The isolation fracture and cavity temperature can be displayed on the front end of the device，Realizing intracavity visualization；The high-voltage voltage transformer box uses electric chassis vehicle upper computer remote control for isolation operation，And added a multi-energy circuit breaker，With electric、Manual closing，Mechanical maintenance、Electrical disconnection、Manual mechanical breaking and other functions。
Meanwhile，Adopt intelligent controller，Power m88 review for AC and DC use，Fewer parts、Advantages of easy maintenance；Install integrated power m88 review system，Provide uninterrupted DC control and protection power m88 review for high-voltage switchgear，At the same time, it can also be used as an underground intelligent measurement and control substation、Ring network switches and other devices provide AC127V backup power m88 review；The low-voltage combined vacuum feed switch adopts a square shell quick-opening structure，Each feeder circuit has an independent main cavity and outlet wiring cavity，The cavity door opens and closes independently，There will be no mutual influence during maintenance or wiring of each circuit，Convenient for maintenance and wiring。
The intelligent upgrade of the central substation，Overcame the difficult problem of unattended power m88 review system，Achieved all-round remote control of the power m88 review system、Preventing overstepping、Precise line selection for ground faults、Precise selection of low-voltage power m88 review、Low voltage power m88 review remote leakage test、Power m88 review remote control、Electric energy measurement、Functions such as cable insulation monitoring and advanced warning of power m88 review hazards，Further optimized the mine power m88 review network，Improved power m88 review reliability，Vigorously promote the construction of intelligent mines。(Wang Yongliang Xu Haozhe)
