Distribution transformer detection compensation control system

Abstract

The invention provides a distribution transformer detection compensation control system which comprises an isolation switch, a circuit breaker, a low-voltage arrester, a transformer capacity tester and two low-voltage power capacitors. The isolation switch is connected with the wire incoming ends of the circuit breaker through a low-voltage connector bar; the wire outgoing ends of the circuit breaker are grounded through the low-voltage arrester; the voltage input ends of the transformer capacity tester are connected with the low-voltage connector bar; the current input ends of the transformer capacity tester are connected with external current signals; the input ends of the first capacitor are connected with the output ends of the transformer capacity tester and the input ends of the second capacitor respectively; the grounding ends of the first capacitor and the second capacitor are mutually connected; and the output ends of the first capacitor and the second capacitor are connected with the low-voltage connector bar. The reactive compensation control system improves the power factor of a grid, reduces loss of a power supply transformer and transmission lines, improves power supply efficiency and improves power supply environment.

Description

[0001] technical field [0002] The invention relates to the technical field of public compensation, in particular to a distribution transformer detection and compensation control system. [0003] Background technique [0004] With the development of the national economy, the task of the national electric power industry is also more difficult. Due to the development of the industry, the reactive power loss in the power grid has increased sharply, which has deteriorated the power quality of the power grid and increased the burden and loss of lines and transformers. Now the country is advocating energy saving and emission reduction, so reactive power compensation in the power grid has attracted more attention. Regardless of industrial loads or daily loads, inductive loads account for a large proportion, such as transformers, asynchronous motors and many household appliances are inductive loads. The natural power factor of these loads is low, and the reactive power consum...

Problems solved by technology

However, when the three-phase load balance in the power supply and distribution system is uncertain, a single phase-splitting compensation or three-phase compensation cannot meet the requirements of reactive power compensation, and cannot provide a stable and continuous compensation for the power system, resulting in circuit Inconvenient control, high failure rate and low power supply efficiency
