The invention provides a gas insulation indoor switch cabinet. The gas insulation indoor switch cabinet comprises a sealed box body, wherein a cavity is formed in the box body; a support is arranged on the left side of the cavity; a combined switch is arranged on the support; an operating mechanism is arranged on the left side wall of the box body and is connected with the combined switch; a first sleeve is arranged on the right side wall of the box body, a touchable bus is arranged on the first sleeve, and the first sleeve is connected with the combined switch; and a second sleeve is arranged on the lower side wall of the box body, and is connected with the combined switch. The gas insulation indoor switch cabinet is reasonable in structural layout, so that the overall volume of the switch cabinet is reduced, and the floor space of the switch cabinet is small; and the gas insulation indoor switch cabinet is convenient to maintain and mount, and through round head screws, discharging of internal components of the switch cabinet can be effectively avoided, and the safety of the product is improved.
Description
Technical field
The present invention 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.
Summary of the invention
Technical problem to be solved by this invention 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 adopts according to a kind of gas-insulated indoor switch cabinet provided by the invention 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.
Gas-insulated indoor switch cabinet provided by the invention 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 adopts gas-insulated indoor switch cabinet provided by the invention to bring 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 invention.
Fig. 2 is the structure chart of removing instrument transformer among the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed description:
As depicted in figs. 1 and 2, embodiment according to a kind of gas-insulated indoor switch cabinet provided by the invention, 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 present invention 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 gas-insulated indoor switch cabinet provided by the invention, 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 gas-insulated indoor switch cabinet provided by the invention, 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.
