OEM High Quality Waterproof Distribution Board Manufacturers – CZW28-12F Outdoor Boundary Load Break Switch – Changan Group
OEM High Quality Waterproof Distribution Board Manufacturers – CZW28-12F Outdoor Boundary Load Break Switch – Changan Group Detail:
General Description
On the 12kV feeding line,when the error happened at one tributary line of the T type link users,normally it will cause the main line or adjacent users power cut accident.the investing make known this kind of accident takes 20%-30% or higher percentage in all power distribution accident,the result is enlarged power cutting scope and cause responsibility disputation.
Mounted a user boundary load break swilch(also name watchdog)at the above T-type connecting point is the ideal solution to the
above accident
Type And Meanings
Main Function Characteristic
Automatically cut single phase earthing fault:when users tributary linecause single phase earthing fault,the boundary switch will open automatically.other distribution line users of the substation and feeding line will be without influence;i$olati〇n interphase short circuit fault automatically.
When the tributary line cause interphase short-circuit fault,boundary switch will open at once after out-wire protection tripping.after the substation reclose.fault line is isolated passively .other distribution users in feeding line resume power supply rapidly(equal to a transient fault).
Quick localization of fault:the tributary line fault cause boundary switch protection action.only the accident user cause power cut and by itself report the dault information.the power company could dispatch wor ker to live investigation；if the boundary switch match with communication,the power company could dispatch worker to live investigation^ the boundary switch match with communication module.it could transmit message to electricity management center.
Monitoring users load,boundary switch could configure wired or wireless communication enclosure to monitor data and transmit ro electricity management center.make the achievement of real-time data monitoring of users load in long distance.
Function of network running.it could be used in network lines;funclion of measurement.monitor voltage.current,frequency and quantity of electricity of lines.and transmit to management center in long distance.Function of harmonic analyzing.to supply retiable basis for pollution administration of electricity net afterwards.
