Active power distribution network power quality monitoring device

Abstract

The invention relates to a power distribution network monitoring technology, and particularly relates to an active power distribution network power quality monitoring device. The device comprises a monitoring assembly, a shell, a supporting assembly, a heat dissipation assembly and a covering plate, wherein the supporting assembly comprises a supporting base; two supporting blocks are fixedly connected to the two sides of the upper end of the supporting base; a first clamping groove is formed in the supporting block; a second clamping groove is formed below the first clamping groove; the heatdissipation assembly comprises a fan motor, the output end of the fan motor is rotationally connected with a fan, air inlet strip holes are formed in the two sides of the supporting base, vent holes are formed in the lower surface of the shell, air outlet strip holes are formed in the two sides of the shell, and the fan motor is electrically connected with an external power source. The shell and the supporting base which are detachably connected facilitate cleaning treatment of the interior of the supporting base, meanwhile, a certain damp-proof effect is achieved, the temperature of the shellis reduced through the heat dissipation assembly, a good heat dissipation effect is achieved, and the heat dissipation efficiency is high.

Description

technical field [0001] The invention relates to distribution network monitoring technology, in particular to an active distribution network power quality monitoring device. Background technique [0002] Electricity is one of the products with the widest range of use, the highest use value and the largest amount of use in modern society. With the development of modern science and technology, major changes have taken place in the load structure of modern power systems, such as the rapid development of loads such as semiconductor rectifiers, thyristor voltage regulators and frequency conversion adjustment devices, steelmaking electric arc furnaces, electrified railways and household appliances. Its non-linear, impulsive and unbalanced power consumption characteristics distort the voltage waveform of the power grid, cause voltage fluctuations and flickers, and three-phase imbalances, and even cause system frequency fluctuations, etc., causing serious interference or pollute.
