Abstract
The utility model discloses a medium-voltage single-bus gas-insulated switchboard with a solid-sealed pole, which comprises a breaker compartment and a cable gas box positioned below the breaker compartment. The transmission mechanism of the breaker compartment is provided with a solid-sealed pole. The lower wire outgoing base of the solid-sealed pole is connected with the cable gas box positioned below the breaker compartment through a conductive rod or a wall bushing with a current transformer. The upper wire outgoing base of the solid-sealed pole is connected with a main bus through a wall bushing. Due to the adoption of the technical scheme of the utility model, since less standard components are adopted to be assembled together, the volume of the pole is reduced. Meanwhile, the medium-voltage single-bus gas-insulated switchboard with the solid-sealed pole is excellent in insulating performance and more compact in structure. Since the secondary installation and connection of the pole with the current transformer in a finger connection mode is no longer needed, the assembly time is shortened. In addition, the material consumption is reduced, thereby facilitating the environmental protection and lowering the cost.
Description
Technical field
The utility model relates to a kind of middle single busbar connection inflation cabinet of pressing, and is specifically related to a kind of middle pressure single busbar connection inflation cabinet of joining pole.
Background technology
The non-pole of prior art needs many optional features in order to tolerate mechanical stress and electric insulation.For example, in non-pole, need come the sharp-pointed edge of covering vacuum arc control device with pressure-equalizing device, also need to lead and fixture keeps good performance when guaranteeing the insulator shell of vacuum tube and branch that elasticity is connected circuit breaker, closing operation.For guaranteeing the insulation property of inflation cabinet, need to have enough spaces clear distance to guarantee dielectric strength between pole and gas tank, pole and pole simultaneously, further make the size of stainless steel gas tank increase, the switch cubicle cost is increased.
Pole is undertaken main insulation property, temperature rise performance and break performance in the inflation cabinet.Non-pole can assemble the vacuum interrupter of different model in identical structure, but needs a lot of add-on assembles.The pole technology is day by day ripe, for gas tank and circuit breaker cooling technology provide new possibility.
Summary of the invention
The purpose of this utility model provides a kind of middle pressure single busbar connection inflation cabinet of joining pole, and it has littler volume, has correspondingly reduced the SF6 gas that needs, and has saved more materials simultaneously.
In order to solve these problems of the prior art, the technical scheme that the utility model provides is: the middle pressure single busbar connection inflation cabinet of joining pole, comprise breaker chamber and the cable gas tank that is positioned at its below, it is characterized in that, transmission mechanism at described breaker chamber is installed a pole, the following outlet seat of described pole passes through contact rod or the wall bushing of belt current instrument transformer and the cable gas tank of below and is connected, and the last outlet seat of pole is connected to main bus bar by wall bushing.
Preferably, between described breaker chamber and the described cable gas tank path is arranged, this path is provided with two air-valve devices.
The utility model effect:
1. the technical solution of the utility model is used the standard component of needs assembling still less, allows to use fixed installation non-standard component still less, makes the electrode volume reduce, and has good insulation property.
2. owing to reduce installation component, thereby have structure more closely, and the fingertip that need not to carry out summation current transformer connects.
3. the utility model assembly is few, has reduced built-up time, because the material that uses reduces, is conducive to environmental protection, has reduced cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 implements the overall structure schematic diagram for middle pressure single busbar connection inflation cabinet one of joining pole of the present utility model.
Fig. 2 is the middle local another enforcement illustration of single busbar connection inflation cabinet of pressing of the present utility model.

Embodiment
For more detailed statement the technical solution of the utility model, below list specific embodiment by the utility model people its effect is described; It is emphasized that these embodiment are not limited to the scope of application of the present utility model for explanation the utility model.
The utility model one embodiment as shown in fig. 1, the middle pressure single busbar connection inflation cabinet of joining pole, comprise that optionally being installed in the outdoor bus PT of main bus bar installs gas tank 2, this bus PT installs gas tank 2 and is connected to voltage transformer 1, three-station 4 is installed in the same bus gas tank, this bus gas tank is arranged on the top of breaker chamber 5, and circuit breaker and transmission device thereof are arranged in the breaker chamber 5, and this transmission device 7 is connected with main bus bar 3 by top set's bus 6; The wall bushing 8 of belt current instrument transformer and cable gas tank 9 are positioned at breaker chamber 5 belows, are provided with cable sleeve 10 in the cable gas tank 9 and are connected row and cable testing sleeve pipe 11, and these times syndeton supports by skeleton 12 and be fixing.Cable gas tank 9 is connected by a path 13 with breaker chamber 5, to guarantee the unanimity of gas pressure intensity; And breaker mechanism 14 and three-station mechanism 15 interconnect in its position, and also are provided with low-pressure cabinet 16 on the skeleton 12; At described breaker mechanism 14 pole 18 is arranged fixedly, the following outlet seat 19 of described pole 18 passes through contact rod or the wall bushing 8 of belt current instrument transformer and the cable gas tank 9 of below and is connected, and the last outlet seat 20 of pole 18 connects top set's bus 6 of main bus bars 3.
In the preferred embodiment of the present utility model, the path 13 between breaker chamber and the cable gas tank is provided with two air-valve devices.When needs overhaul, can close the upper end valve in two air valves like this, dismantle the cable gas tank separately; Perhaps close the lower end valve in two air valves as required, dismantle breaker chamber separately; And do not need integral demounting to open, increased flexibility and the fail safe safeguarded.
