Abstract
The utility model relates to a power supply box. A three-phase unbalanced correcting power supply box comprises a box body, and a ZigZag transformer, an input unit module, a negative sequence compensation unit module and a zero sequence compensation unit module which are arranged in the power supply box. The zero sequence compensation unit module and the negative sequence compensation unit module adopt drawer-type structures; the wire connection on the terminal block on the left side can be dismantled, and then the entire modular unit is directly drawn to be integrally detached from the entire machine body in the overhaul process; and the structure has the benefit that when the zero sequence compensation unit module or the negative sequence compensation unit module is in failure during the operation of the entire machine, the fastest solution that the modular unit is directly dismantled and replaced is adopted; moreover, the power supply box has the characteristics of simple structure and convenient maintenance.
Description
Technical field
The utility model relates to a kind of consumer unit.
Background technology
In China's urban and rural power grids, adopt the three-phase four-wire system distribution system in a large number.Owing to there being reasons such as a lot of single-phase loads, electricity consumption asynchronism, the three-phase imbalance on the power distribution network always exists.The unbalanced operation of distribution transformer, the increase of neutral current can increase copper loss, the iron loss of transformer, and neutral current is crossed conference and blown the neutral line, influence the safe operation of transformer, cause imbalance of three-phase voltage, reduce the quality of power supply.
Existing power distribution network three-phase equilibrium compensation arrangement is by ZigZag transformer, input unit module, negative sequence compensation unit module and zero sequence compensation unit module, this device generally is fixedly installed in the casing, when zero sequence compensation unit module or negative sequence compensation module broke down, maintenance was not very convenient.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of three-phase imbalance and proofreaies and correct consumer unit, and this consumer unit has characteristics simple in structure, easy to maintenance.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
Three-phase imbalance is proofreaied and correct consumer unit, this consumer unit comprises casing and is arranged on the interior ZigZag transformer of consumer unit, the input unit module, negative sequence compensation unit module and zero sequence compensation unit module, the ZigZag transformer, the input unit module, negative sequence compensation unit module and zero sequence compensation unit module are connected by lead, casing is by top cover, cabinet, door-plate, portable plate and fixed head constitute, the ZigZag transformer is fixedly installed on the fixed head, the input unit module bottom is fixed on fixed head and fixes with the sidewall of cabinet, negative sequence compensation unit module and zero sequence compensation unit module are fixedly installed on respectively on two portable plates, and be respectively equipped with slide rail up and down side by side in the two side of cabinet, described two portable plates are provided with movable pulley, and movable pulley is arranged on the slide rail.
The utility model is owing to adopted above technical scheme, zero sequence compensation unit module and negative sequence compensation unit module adopt drawer-type structure, directly whole modular unit is pulled out behind the line on the left of in the process of maintenance, can dismantling on the terminal board, break away from whole fuselage integral body, the benefit of this structure is exactly in the middle of the entire machine operation, when zero sequence compensation unit module or negative sequence compensation module break down, settling mode is exactly directly to change this modular unit the most efficiently, have characteristics simple in structure, easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
