6KV10KV Outdoors HV Line Full Automatic Compensation Cabinet
Product name: 6KV10KV Outdoors HV Line Full Automatic Compensation Cabinet
Classification: high-voltage complete equipment series
Product overview
According to the 6KV10KV Outdoors HV Line Full Automatic Compensation Cabinet of the 6KV, 10KV supply bus, the high-voltage automatic reactive power compensation device automatically tracks the capacitor group of the control system for automatic reactive power tracking compensation, and the power factor is above 0. 9.Greatly optimize the power quality, reduce loss and reduce consumption, and improve the transmission capacity of the power transmission and distribution system.
Model meaning
For example: TBBZ10-1500(600 + 900) -AK indicates voltage of 10kV, device capacity of 1500kvar, two groups, 600kvar, 900kvar, single star wiring, and open triangle voltage protection.
Regular service conditions
Elevation: not high as 1000m; ambient temperature: -25~ + 55℃: relative humidity: not exceeding 85%: no explosive dangerous medium, the surrounding medium shall not contain corrosive and destructive insulation gas and conductive medium, and shall not allow full of steam and serious mold.
Product characteristics
The device can operate for a long time at the steady state overvoltage of 1. 1 times the rated working voltage: the device can operate continuously at the value of less than 1. 3 times the rated current of the capacitor group: the device is cut by vacuum contactor, can operate frequently; each group of capacitor is equipped with discharge coil, which can drop below 50 V in 5 seconds; each set of capacitor can use relay protection or computer protection control unit, realize overcurrent, voltage imbalance, undervoltage and overvoltage protection of the system.When a group of capacitors fail, this group of capacitors can be cut off, does not affect the use of other capacitors: a single capacitor is protected by spray by injection circuit, each group is equipped with lightning arrester starting overvoltage and lightning overvoltage protection: large screen LCD display controller, display system voltage, current, power factor in real time; has RS232/RS485 standard communication interface, and can achieve "four remote" function: each group can be configured to inhibit closing surge flow or inhibit harmonic amplification.
