Embodiment 1

[0028] An intelligent high-voltage reactive power compensation double-sided switchgear, such as figure 1 and Figure 6 As shown, including compensation module power distribution cabinet 1 and incoming line module power distribution cabinet 2;

[0029] Both the compensation module power distribution cabinet 1 and the incoming line module power distribution cabinet in the intelligent high-voltage reactive power compensation double-sided switchgear of this embodiment adopt SZGW-12 type cabinets, and the size is 1100*1200*2300mm.

[0030] Further, such as figure 2 As shown, the compensation module power distribution cabinet 1 includes a first shell 113. The interior of the first shell 113 is divided into three layers. The top of the top layer is equipped with three wall-through bushings 17 that are evenly spaced and linearly arranged. A horizontal busbar 11 is installed in the bushing 17, and the upper branch line 12 is connected to the horizontal busbar 11. The first instrumen...

Embodiment 2

[0039] As a second preferred embodiment of the present invention, such as image 3 As shown, the topmost outer wall of the first housing 113 is provided with a first instrument door 114, and the first instrument door 114 is provided with three voltmeters 115 and a plurality of first indicator lights 116 arranged evenly and equidistantly. The middle layer and the bottom layer share a first lower door 118, and two first observation windows 117 are installed on the surface of the first lower door 118.

[0040] Further, one side edge of the first instrument door 114 and the first lower door 118 is connected to the first shell 113 through a hinge.

[0041] In addition, if Figure 5 As shown, the topmost outer wall of the second housing 215 is provided with a second instrument door 217, and three ammeters 218, an automatic compensator 216, several second indicator lights 219 and a microcomputer protector 222 are installed on the second instrument door 217. The middle layer and the...

Abstract

The present invention relates to the technical field of power distribution equipment, in particular to an intelligent double-sided switch cubicle for high-voltage reactive power compensation, which comprises a compensation module distribution cabinet and an incoming line module distribution cabinet. The compensation module distribution cabinet comprises a first shell; the inside of the first shellis divided into three layers; the top of the topmost layer is equipped with three evenly spaced wall bushings in a linear arrangement; a horizontal bus bar is equipped in each wall bushing and the horizontal bus bar is connected with an upper branch line. In the invention, the second shell and the first shell share the three wall bushings and the horizontal bus bar so that the materials of the wall bushings and the horizontal bus bar are saved and the cost is reduced; the compensation module distribution cabinet and the incoming line module distribution cabinet are closely connected so that the floor space and the overall height are reduced and the materials of the first shell and the second shell are saved. The compensation module distribution cabinet and the incoming line module distribution cabinet are designed in a unified manner. The two modules can be freely combined and installed. The shells and the mechanical parts of the two modules are universal so that the processing time of the shells is greatly saved.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to an intelligent high-voltage reactive power compensation double-sided switchgear. Background technique [0002] At present, the high-voltage capacitor devices on the market have the following problems: large volume, high cabinet shape, difficult to transport; most of them are switched manually, and it is difficult to realize automatic switching; due to the large cabinet body, it occupies a large area, and the power distribution room needs to be covered The cabinet is large, so the amount of copper busbar is large and the cost is high; due to the high cost, the number of high-voltage compensation circuits is small, the compensation is not refined, and the power factor is difficult to reach 0.9; in the Southern Power Grid area, high-voltage compensation is used outdoors Type installation can not realize the assembly production in the factory, all are assembled o...
