(1) Purpose
JP series multi-functional low-voltage integrated distribution box is widely used in substations, factories, industrial and mining enterprises, large power plants, petroleum and chemical enterprises, large steel plants, high-rise building power centers, and 10/0.4KV outdoor substation low-voltage side of urban and rural power grids; It has the functions of power distribution, power metering, data acquisition, voltage monitoring, over-current protection, low-voltage lightning protection, power failure protection and reactive compensation; It is also applicable to the corresponding on-site power distribution control, and can also be used as a supporting auxiliary device for other power distribution equipment. The product complies with GB7251.12-2013 Low voltage Switchgear and Control Equipment in Sets - Part 2: Power Switchgear and Control Equipment in Sets and GB/T 15576-2008 Low voltage Complete Reactive Power Compensator.
⑵ Product characteristics
1) Automatic dynamic target value setting can prolong the service life of compensation capacitor and switching device, thus improving the service life of the whole equipment;
2) Remote automatic judgment and alarm for capacitor and switching device fault or damage;
3) It has overvoltage, overload, undervoltage, undercurrent, short circuit and other protection functions;
4) When the capacitor is switched on or off, the data transmission of cell carrier integrated reading will not be affected;
5) Three phase imbalance automatic fine adjustment, zero crossing switching, no inrush current.
