An AVC voltage controller for intelligent distribution network

Abstract

The invention provides an AVC voltage controller for an intelligent distribution network, which comprises a voltage controller main body, an insulator string, a hollow radiating fin and a baffle. Fourinsulator strings are mounted on the top of the voltage controller main body, and a plurality of rows of vertical hollow fins are mounted on the front side and the rear side of the insulator strings,and left and right sides of the insulator strings are respectively mounted with baffles through bolts. The invention has the advantages that: 1) the voltage can be adjusted automatically according tothe degree that the actual voltage value deviates from the rated range, and the effect is better; 2) adde a hollow heat sink, which has good heat dissipation effect, and can automatically start thatair pump when the temperature is too high, so that the air flow is formed inside the air pump, and the heat dissipation effect can be greatly increase without affecting the sealing property, and the safety can be increased; 3) It has the functions of overheat alarm and positioning, which can alarm in case of malfunction, so it is convenient for the staff to quickly determine its position and carryout maintenance and repair work, so as to avoid losses.

Description

technical field [0001] The invention relates to an intelligent distribution network AVC voltage controller, which belongs to the technical field of electric power equipment. Background technique [0002] During the operation of the power system, it is of great significance to adjust the voltage of the power system so that its variation does not exceed the specified allowable range, which can ensure the stability of the power system and the safe and economical operation of various power equipment and appliances. Voltage is one of the basic indicators to measure power quality, and it is a sign reflecting the balance and reasonable distribution of reactive power in the power system. Reactive power balance and voltage adjustment are factors that must be considered in power system planning and design. Voltage adjustment is performed to ensure voltage quality. Running one of the main tasks of the scheduler. Unstable grid voltage will cause many hazards. Low grid voltage may cause...

AI Technical Summary

Problems solved by technology

Unstable grid voltage will cause many hazards. Low grid voltage may cause grid oscillation, system disassembly, large-scale power outages, leading to water, gas, and telecommunications interruptions, etc., seriously affecting people's lives and social security. High grid voltage will accelerate The insulation aging of electrical equipment reduces the service life of electrical equipment, increases the no-load loss of electrical equipment such as transformers, and increases line loss. Therefore, voltage regulation is of great significance to power systems.

However, the current AVC voltage controllers for distribution networks on the market only have a single adjustment, and cannot automatically select a method to adjust the voltage according to the degree to which the actual voltage value deviates from the rated voltage range. There is still room for improvement in the adjustment effect, and the market The AVC voltage controller in the distribution network does not have a multi-level heat dissipation function, the heat dissipation performance is constant, and the resource utilization rate is low
