Abstract
The utility model provides a gas insulated indoor switch cabinet. The cabinet comprises a sealed box body provided with a hollow cavity, a bracket arranged on the left side of the hollow cavity, a combination switch arranged on the bracket, an operation mechanism arranged on the left side wall of the box body and connected with the combination switch, a first sleeve arranged on the right side wall of the box body and connected with the combination switch, a touchable type bus arranged on the first sleeve, and a second sleeve arranged on the lower side wall of the box body and connected with the combination switch. By adopting the reasonable structure layout, the size of the whole switch cabinet is reduced, the occupancy area is small, the cabinet is easy to maintain and install, and button head screws are used, so as to effectively avoid the discharge phenomenon of the internal components of the switch cabinet and improve the safety of the product.
Description
Technical field
The utility model relates to a kind of gas-insulated indoor switch cabinet.
Background technology
Gas-insulated cabinet is compared the advantage that has very with general air insulation cabinet.Adopt the Compressed Gas (SF6 gas) of excellent performance, greatly improved insulation property, SF6 gas-insulated performance is 2～3 times of air, and along with the rising of electric pressure, advantage is more obvious.This advantage is convenient to design less cabinet size, is conducive to develop to miniaturization.Adopt the hermetic type structure, can not be subjected to the impact of extraneous environment (such as condensation, filth, toy and chemical substance etc.), be applied to abominable place.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, and the energising operation continuity that a kind of floor space is little, degree of protection is high, higher, the gas-insulated indoor switch cabinet of high reliability are provided.
The main technical schemes that a kind of gas-insulated indoor switch cabinet that provides according to the utility model adopts is: comprise seal case, has a cavity in the described casing, be positioned at described cavity the left side be provided with support, on the described support unit switch is installed, one operating mechanism is installed on the left side wall of described casing, described operating mechanism is connected with described unit switch, the first sleeve pipe is installed on the right side wall of described casing, on described the first sleeve pipe the very touch-type bus is installed, described the first sleeve pipe is connected with described unit switch, the second sleeve pipe is installed on the lower wall of described casing, and described the second sleeve pipe is connected with described unit switch.
The gas-insulated indoor switch cabinet that the utility model provides also can have following attached technical characterictic:
Described the first sleeve pipe all is connected with described unit switch by cheese head screw with described the second sleeve pipe.
Instrument transformer also is installed on the described cabinet, and described instrument transformer is connected with described the second sleeve pipe.
Described the first sleeve pipe and described the second sleeve pipe all and between the described casing are provided with sealing gasket.
The upper end of described casing left side wall is equipped with a density meter.
Described operating mechanism adopts shaft seal to be connected with described casing.
The bottom of described cabinet is equipped with a pressure relief device.
The beneficial effect that the gas-insulated indoor switch cabinet that adopts the utility model to provide brings is: by rational topology layout, reduced the volume of switch cubicle integral body, realize that floor space is little, be convenient to maintenance and install, pass through to use cheese head screw, the electric discharge phenomena of inside switch cabinet element can have effectively been avoided, the fail safe that has improved product; Degree of protection is high, good seal performance, higher energising serviceability, enough gas-insulated gaps, uniformly electric field design, high reliability; Pressure relief device by bottom of cabinet bulk discharges the cabinet air pressure inside to keep the stability of air pressure inside.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the structure chart of removing instrument transformer in the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
As depicted in figs. 1 and 2, the embodiment of a kind of gas-insulated indoor switch cabinet that provides according to the utility model, comprise seal case 1, has a cavity in the described casing 1, be positioned at described cavity the left side be provided with support 2, on the described support 2 unit switch 3 is installed, one operating mechanism 4 is installed on the left side wall of described casing 1, described operating mechanism 4 is connected with described unit switch 3, the first sleeve pipe 5 is installed on the right side wall of described casing 1, on described the first sleeve pipe 5 very touch-type bus 51 is installed, described the first sleeve pipe 5 is connected with described unit switch 3, and the second sleeve pipe 6 is installed on the lower wall of described casing 1, and described the second sleeve pipe 6 is connected with described unit switch 3, on the described cabinet 1 instrument transformer 7 is installed also, described instrument transformer 7 is connected with described the second sleeve pipe 6.The utility model has reduced the volume of switch cubicle integral body by rational topology layout, realizes the energising operation continuity that floor space is little, degree of protection is high, higher, the characteristics of high reliability.
Referring to Fig. 2, according to the gas-insulated indoor switch cabinet that the utility model provides, described the first sleeve pipe 5 all is connected with described unit switch 3 by cheese head screw 8 with described the second sleeve pipe 6.By using cheese head screw 8 described the first sleeve pipes 5 of fixed installation and described the second sleeve pipe 6 on unit switch 3, the electric discharge phenomena of inside switch cabinet element can have effectively been avoided, the fail safe that has improved product.
Referring to Fig. 1 and Fig. 2, according to the gas-insulated indoor switch cabinet that the utility model provides, described the first sleeve pipe 5 and described the second sleeve pipe 6 all and be provided with sealing gasket 9 between the described casing, described operating mechanism 4 adopts shaft seal 10 to be connected with described casing 1.Be provided with sealing gasket 9 respectively and between the first sleeve pipe 5 and the second sleeve pipe 6 at casing 1, improved the sealing property of product, improved coefficient of safety.
Referring to Fig. 2, according to the gas-insulated indoor switch cabinet that the utility model provides, the upper end of described casing 1 left side wall is equipped with a density meter 11 with the air pressure in the pilot switch.
Referring to Fig. 2, according to the gas-insulated indoor switch cabinet that the utility model provides, the bottom of described cabinet 1 is equipped with a pressure relief device 12.When the air pressure of inside switch cabinet acquired a certain degree, the pressure relief device 12 by cabinet 1 bottom discharged the cabinet air pressure inside to keep the stability of air pressure inside.
