Abstract

The utility model relates to an ultrahigh-voltage transmission substation device, in particular to an ultrahigh-voltage open-type combined electrical appliance. The electrical appliance comprises a current transformer10, circuit breakers 1 and an insulating strut 2, and is characterized in that two circuit breaker 1 are fixed on the insulating strut 2; the insulating strut 2 and a circuit breaker rotating-operating device 8 are fixed on a rotary chassis 3; a bearing 5 and a plane bearing 6 are arranged between the rotary chassis 3 and a base 4; an electric mechanism 7 connected with the rotary chassis 3 is arranged in the base 4; moving contacts of an isolating switch 9 are fixed on the end parts of the two circuit breakers 1; and fixed contacts of the isolating switch 9 are fixed on the current transformer 10 and the top end of an insulating porcelain pillar 11. As a new combination mode is adopted, the electrical appliance has the advantages that the electrical appliance is novel in structure and low in material consumption, and occupies land which only one half the area of the prior ultrahigh-voltage open-type combined electrical appliance, thereby saving precious land resources.

Description

The superhigh pressure open combined electri cappliance

Technical field

The utility model relates to a kind of ehv power transmission station equipment, particularly a kind of superhigh pressure open combined electri cappliance.

Background technology

Known superhigh pressure open combined electri cappliance is that isolating switch and current transformer make up, or isolating switch, current transformer, circuit breaker made up, this combination just is arranged on the fixed contact of isolating switch on the current transformer or on the circuit breaker, the moving contact of isolating switch is still operated by the operating mechanism of isolating switch, the very numerous and diverse and dispersion of this high voltage power transmission and transforming station equipment makes that the floor space of transformer station is bigger.

The utility model content

The purpose of this utility model is in order further to dwindle the floor space of superhigh pressure transformer station, in the superhigh pressure open combined electri cappliance that provides more than a kind of 363kV of being adapted to electric pressure.

Technical solutions of the utility model are to realize like this.The utility model contains current transformer, isolating switch, circuit breaker and circuit breaker insulation column, it is characterized in that two circuit breakers are fixed on one and thoroughly do away with on the edge pillar, the powder operation device of insulation column and circuit breaker all is fixed on the swivel base, bearing and plane bearing are installed between swivel base and base, the motor drive mechanism that is connected with swivel base is installed in base, on the end of two circuit breakers, be fixed with the moving contact of isolating switch, be provided with the fixed contact of isolating switch on the top of current transformer and insulation porcelain knob.

Good effect of the present utility model is:

The utility model is owing to adopt new combination, and structure is novel, and materials are less, and land occupation has only half of former superhigh pressure open combined electri cappliance occupation of land.Be installed on the swivel base owing to the circuit breaker insulation column again, has spinfunction, on two ends of two circuit breakers trigger device is arranged, therefore, circuit breaker has the function of isolating switch, so just saved original big isolating switch, reduced the floor space of transformer station greatly, the utility model can be saved a large amount of valuable land resources.

Description of drawings

Fig. 1 is the utility model structural representation, also is Figure of abstract.

Fig. 2 is the utility model A-A structure for amplifying schematic diagram.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

In the drawings, two circuit breakers 1 (actual is two arc control device of circuit breaker) are fixed on the insulation column 2, insulation column 2 and circuit breaker rotation powder operation device 8 are fixed on the

swivel base

3,4 of swivel base 3 and bases are equipped with bearing 5 and plane bearing 6, bearing 5 and plane bearing 6 can make swivel base 3 rotate reposefully, the motor drive mechanism 7 that is connected with swivel base 3 is installed in base 4, on the end of two circuit breakers 1 (two arc control device of circuit breaker), be fixed with the moving contact of isolating switch 9, on current transformer 10 and insulation porcelain knob 11 tops, be fixed with the fixed contact of isolating switch 9.The fixed contact formation isolating switch 9 of fixing isolating switch 9 on the moving contact summation current transformer 10 of fixing isolating switch 9 and insulation porcelain knob 11 tops on the end of two circuit breakers 1 (two arc control device of circuit breaker), isolating switch 9 can be more than two.

During use, utilize circuit breaker rotation powder operation device 8 to start motor drive mechanism 7, make swivel base 3 rotations that are connected in motor drive mechanism 7, two circuit breakers 1 (two arc control device of circuit breaker) that swivel base 3 drives on pillar 2 again rotate, rotation 90 is a stop bit when spending, also the i.e. fixed contact of isolating switch 9 disconnection that is separated on the moving contact of the isolating switch 9 on two circuit breakers 1 (two arc control device of circuit breaker) end and the current transformer 10 and the porcelain knob 11 that insulate forms two tangible isolation fractures; Rotate 90 degree or backward rotation 90 degree again for connecting the position, the fixed contact of isolating switch 9 joins on the moving contact that two circuit breakers 1 this moment (two arc control device of circuit breaker) are gone up fixing switch 9 and the current transformer 10 and the porcelain knob 11 that insulate.

Claims
