Distribution box distribution transformation terminal of improving reactive compensation efficiency

Abstract

The present invention relates to a distribution box distribution transformation terminal of improving the reactive compensation efficiency. The distribution box distribution transformation terminal comprises a box body and an acquisition processor, the acquisition processor is connected with a reactive compensation controller and is equipped with an RS-485 communication interface, and the reactive compensation controller depends on a control signal issued by the acquisition processor to realize the reactive compensation. The RS-485 communication interface is connected with a residual current operated protector, and the box body is equipped with a branch loop monitoring device. The acquisition processor is connected with a digital signal processor, and a GPRS communication device which is connected with a master station normally is arranged outside the box body. The advantages of the present invention are that by using the acquisition processor to issue the control signal, a reactive power compensator compensates the voltages in a distribution box, a power factor of a power grid, the power supply efficiency and the power supply environment are improved, and the loss of a power supply transformer and the transmission lines are reduced; by using the acquisition processor to issue the control signal, the automation control of the reactive power compensator is realized, and the reactive power compensator can compensate the power in one step.

Description

technical field [0001] The invention relates to a distribution box terminal for improving reactive power compensation efficiency. Background technique [0002] At present, the distribution box constitutes a low-voltage forest according to the electrical wiring. It is required to assemble the switchgear, measuring instrument, protective device and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen width, which can distribute electric energy reasonably and facilitate the connection of the circuit. Opening and closing operation, during the use of the existing distribution box, due to different factors, the loss of the network and the decline in the quality of the power grid are caused. However, the reactive power compensation system in the existing distribution box is manually operated. , causing the compensation power not to be in place in one step, the impact current is too large, the system characteristics are easy to drift, the maintenance cost is...
