Description
(1) technical field:
The utility model belongs to high-voltage switch equipment, is mainly used in electric power system.
(2) technical background:
The power industry high speed development drives the common progress of high voltage electric equipment manufacturing simultaneously.Medium-voltage distribution equipment has a large capacity and a wide range especially, is widely used in industrial and mining enterprises, power plant, urban and rural power grids etc., and its security reliability directly affects the safety of national economy and people's lives and properties.
Application feature from domestic switchgear, mainly based on air-insulated open type switchgear, but the insulation margin alternate and over the ground of this series products is little, can not meet full operating mode service requirement, especially in filth, humidity, condensation, and place such as power plant, the insulation fault rate is high especially, and uses limited in the high altitude localities.Therefore manage to strengthen the insulation level of existing switchgear and improve work such as insulating part material extremely urgent.I think that the dielectric that only changes is only the effective way that improves the switchgear insulation level; The size of switch is dwindled.Therefore adopt the Cubicle Gas-Insulated Switchgear of sulfur hexafluoride gas-insulating to arise at the historic moment.This equipment is subjected to the ambient atmosphere condition effect hardly.Therefore under the condition of plateau and pollution severity, more can bring into play its advantage; And the set-up time is short, floor space is little, maintenance period is long, maintenance cost is low, utilance is high, the person and device security height, power supply are reliable, be widely used in the narrow and small place of humidity, condensation, filth, chemical gas burn into, densely populated urban district, skyscraper, places such as subway and underground substation.
(3) summary of the invention:
In order to improve the reliability of power system power supply, optimize electric power system, reduce the wasting of resources, improve fail safe, the reliability of electric power system.The utility model has not only been realized the full-closed structure of high voltage device, all high voltage devices are sealed in the housing that is filled with sulphur hexafluoride, and broken conventional construction of switch form, be that electric power system provides a kind of brand-new power supply unit with a kind of brand-new version
The technical scheme that its technical problem that solves the utility model adopts is: the utility model is sealed in each function element such as circuit breaker, isolation-earthed switch, main bus bar in the housing that is filled with sulfur hexafluoride gas, increase insulation margin greatly, and be not subjected to the influence of external environment.The three-phase of all simultaneously function element arranges that the relative cabinet front panel of A, B, C three-phase of high pressure element such as the circuit breaker, isolation-earthed switch, bus of the box type gas insulating metal enclosed switchgear that is different from international renowned companies such as ABB, Siemens, Alstom is the left, center, right structural configuration, but A, B, C three-phase, in-line was arranged before and after the front panel of cabinet was relatively.The more important thing is isolation and the ground connection that to realize circuit by the arc control device bucket of circuit breaker around a main axis rotation, realized the integrated structure design of circuit breaker and isolation-earthed switch.
The beneficial effects of the utility model: the arc control device by circuit breaker can rotate the isolation and the ground connection of realizing circuit, under the prerequisite of finishing the electric power system identical function, can reduce one group of isolation, earthed switch, the electric power system element reduces, chain compact more, reliable, also reduced the cost of product.All high voltage devices all are enclosed in the housing that is filled with sulphur hexafluoride simultaneously, be not subjected to the influence of external environment, insulation is reliable, in-line was arranged before and after the front panel of the A of each function element, B, each relative cabinet of C three-phase was, can significantly reduce the width of cabinet, floor space is 30% of a conventional air insulation switch cubicle of the same type, and 65% of inflation cabinet conventional of the same type has significantly reduced floor space.Adopting the bus coupling, be convenient to on-the-spot Installation and Debugging, is the desirable substitute products of traditional electrical power trans mission/distribution system equipment
