Abstract
The invention relates to a switch filed and provides a high voltage switch gear. The high voltage switch gear comprises: a busbar possessing a three-phase conductor, a phase conductor, a busbar isolation switch, a single-phase power switch and a switch shell. An input terminal of the busbar isolation switch is connected with the corresponding phase conductor. The busbar isolation switch and the phase conductor are arranged in a busbar module of the three-phase conductor. The busbar isolation switch is connected with the corresponding single-phase power switch on an output side. By using the high voltage switch gear of the invention, the direct connection of three single-stage power switches is allowed in the high voltage switch gear through the busbar module so that a connection mode can be greatly simplified. Therefore, a switch shell space can be saved. The switch gear is convenient to use and cost is low.

Technical field
The present invention relates to a kind of switchgear, more particularly, relate to a kind of high voltage switchgear.
Background technology
Along with the development of human electric utility, electric switching system is also more and more, yet a lot of switchgear exists inconvenience, uneasy congruent problem.Inner complex connection often appears in electrical high voltage switching station, needs bigger problems such as shell space demand.
Summary of the invention
The technical problem that the present invention will solve is, to the inner complex connection of high voltage switchgear that prior art exists, needs the defective of bigger switch case, and a kind of high voltage switchgear is provided.
The present invention provides a kind of high voltage switchgear, comprises bus-bar, phase conductor, bus-bar isolating switch, single-phase power switch and a switch case with three-phase conductor, it is characterized in that, wherein,
The input of bus-bar isolating switch connects corresponding phase conductor;
Bus-bar isolating switch and phase conductor are arranged in the bus-bar module of three-phase conductor;
The bus-bar isolating switch is connected with corresponding single-phase power switch at outlet side.
Preferably, also comprise a distribution module, saidly comprise three interfaces, three single-phase interfaces and three phase conductors with joining module, wherein, phase conductor is guided the single-phase interface into from three interfaces respectively.
The high voltage switchgear of embodiment of the present invention; Have following beneficial effect: the inside of high voltage switchgear allows three single-stage power switchs directly to connect through the bus-bar module, has greatly simplified connected mode, thereby has saved the switch case space; Make it convenient, cost is cheaper.
Embodiment
The present invention provides a kind of high voltage switchgear, comprises bus-bar, phase conductor, bus-bar isolating switch, single-phase power switch and a switch case with three-phase conductor, and wherein, the input of bus-bar isolating switch connects corresponding phase conductor; Bus-bar isolating switch and phase conductor are arranged in the bus-bar module of three-phase conductor; The bus-bar isolating switch is connected with corresponding single-phase power switch at outlet side.
Switchgear is implemented as high voltage switchgear metallic packaging, gas isolated.Sulphur hexafluoride is used as insulating gas.Alternatively, nitrogen or carbon dioxide also can be used as insulating gas.
Switchgear comprises the bus-bar with three phase conductors.These three phase conductors are directed in the first bus-bar module in the scope of the first output feeder panel, and further are drawn towards the bus-bar module of the adjacent feeder panel that is not illustrated here.
The housing of the first bus-bar module is constructed to cylindrical; Wherein the axis of the housing of the phase conductor of bus-bar and the first bus-bar module is directed abreast. and it has three flange connectors the first bus-bar module 40, is used for the connection of power switch housing or other module.These flange connectors radially are disposed in highlightedly and along outer body line on the outside of cylindrical housings of the first bus-bar module with adjoining.
In addition, the first bus-bar module all respectively has one at this flange connector that is not illustrated at each end face of its cylindrical housings, is used for connecting respectively other bus-bar module or other element, such as Geiger.
The first bus-bar isolating switch is assigned to first phase conductor; This first bus-bar isolating switch is connected with first phase conductor at input side. at this; The bus-bar isolating switch is disposed in the first bus-bar module equally. correspondingly; Second phase conductor is connected with the second bus-bar isolating switch, and the third phase conductor is connected with the 3rd bus-bar isolating switch.
In addition, each bus-bar isolating switch respectively is assigned with one at this earthed switch that is not illustrated, and this earthed switch is connected with the output of related bus-bar isolating switch.The bus-bar isolating switch may be implemented as the isolation earthing switch that the switchgear that separates perhaps is implemented as combination with the earthed switch that is assigned with at this. in the case; The bus-bar isolating switch is especially implemented as the portable isolating switch of plug-in strip, but also can imagine as the structure of rotary isolation switch.
The first bus-bar isolating switch is assigned with first power switch; This first bus-bar isolating switch is connected with this first power switch at outlet side. and first power switch is disposed in the first power switch housing that separates at this, and this first power switch housing is fixed on first flange connector of the first bus-bar module.
Correspondingly, the second bus-bar isolating switch is assigned with second power switch. and at this, second power switch is disposed in the second power switch housing of separation, and this second power switch housing is fixed on second flange connector of the first bus-bar module.The 3rd bus-bar isolating switch is assigned with the 3rd power switch.The 3rd power switch is disposed in the 3rd power switch housing of separation, and the 3rd power switch housing is fixed on the 3rd flange connector of the first bus-bar module.
Bonding conductor between bus-bar isolating switch and the power switch is conducted through each in three flange connectors of the first bus-bar module respectively dividually at this.
The high voltage switchgear of embodiment of the present invention; Have following beneficial effect: the inside of high voltage switchgear allows three single-stage power switchs directly to connect through the bus-bar module, has greatly simplified connected mode, thereby has saved the switch case space; Make it convenient, cost is cheaper.
The present invention describes through embodiment, and those skilled in the art know, under the situation that does not break away from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these characteristics and embodiment.In addition, under instruction of the present invention, can make amendment to these characteristics and embodiment can not break away from the spirit and scope of the present invention to adapt to concrete situation and material.Therefore, the present invention does not receive the restriction of specific embodiment disclosed herein, and all interior embodiment of claim scope that fall into the application belong to protection scope of the present invention.
