Description
Technical field
The utility model relates to the corollary equipment in a kind of power supply unit, relates in particular to a kind of loop-network switch cabinet.
Background technology
At present, ring network power supply increasingly extensive application in the urban and rural power grids distribution system.Like product on the market has following deficiency or shortcoming:
At first, loop-network switch cabinet mainly adopts SF6 (sulphur hexafluoride) gas as insulation and arc-extinguishing medium.Yet SF6 gas itself has negative effect to environmental protection; And SF6 gas can produce noxious substance under electric field action or behind the short circuit interruption, and then may damage people's health or contaminated environment.
Secondly, SF6 gas is also very high to the seal request of casing.In case, then will cause producing the danger that whole switch cubicle is blasted because the box sealing effect is bad.
Moreover, adopt SF6 generally all to adopt fuse combined electric apparatus as the short-circuit protection device as the loop-network switch cabinet of insulation and arc-extinguishing medium.Yet be subjected to the influence of fuse rated current, substantially all below 1600kVA, this can not satisfy the requirement of big capacity power supply on the market to the capacity of protection transformer fully.
Therefore, be necessary to provide a kind of loop-network switch cabinet of improvement, so that overcome above-mentioned various shortcoming and defect part.
The utility model content
The utility model provides a kind of loop-network switch cabinet, and it reaches the arc extinguishing purpose by vacuum; Simultaneously in use can not cause murder by poisoning, can not cause contaminated environment human body; Gas leakage reduced high request, even also can not blasted to sealing; And can have anti-condensation, rainproof effect; Improve rated current and operation-current, thereby increased the capacity of transformer.
For this reason, the utility model provides a kind of loop-network switch cabinet, comprising: the guidance panel that is positioned at the front upper of ring main unit; Be positioned at the spring operating mechanism at ring main unit front upper and guidance panel relative position place; One end attended operation panel and the other end connect the connecting rod of spring operating mechanism; Be positioned at the vacuum interrupter at ring main unit middle part; Insulated tension pole between spring operating mechanism and vacuum interrupter; Be positioned at the PC insulating cover at ring main unit middle part; Be positioned at the gas tank of ring main unit bottom, the switch main body parts be installed in it, and be filled with dry gas or nitrogen in it; Be fixed on the wall bushing on the gas tank, the top of wall bushing is connected with vacuum interrupter, and the bottom then is connected with the outer cable plug; And vacuum circuit-breaker or vacuum load switch, it is positioned at the top of wall bushing, and the two ends of vacuum circuit-breaker or vacuum load switch are connected with wall bushing and insulated tension pole respectively.
Advantage of the present utility model is: form vacuum environment at the loop-network switch cabinet suitable position and reach the arc extinguishing purpose; Adopt organic material and AIR MIXTURES as the external insulation medium simultaneously, in use can not cause murder by poisoning, more can not cause contaminated environment human body; Gas leakage reduced high request, even also can not blasted to sealing; And can have anti-condensation, rainproof effect; The combination of vacuum circuit-breaker and vacuum load switch has improved rated current and operation-current, thereby has increased the capacity of transformer.
Below with reference to drawings and the specific embodiments the utility model is described further.
Description of drawings
Fig. 1 is the structure chart of the utility model loop-network switch cabinet.
Embodiment
The utility model loop-network switch cabinet is formed by vacuum circuit-breaker unit and vacuum load switch unit combination.And can be combined into 6 unit casing altogether at most.Its compact conformation, little, the good looking appearance of volume mainly are used in branch in city and the rural area power supply-distribution system, close load current, overload and short-circuit protection, are specially adapted to outdoor rugged environment.
With reference to figure 1, the utility model loop-network switch cabinet comprises a plurality of unit, such as 3 unit (a vacuum circuit-breaker unit and two vacuum load switch unit).
Particularly, each unit of the utility model loop-network switch cabinet comprises:
Connecting rod 2, one end connect described guidance panel 1, and the other end then connects described spring operating mechanism 3, are used to transmit the motion between spring operating mechanism 3 and the guidance panel 1;
Be positioned at the vacuum interrupter 6 at described ring main unit middle part;
Vacuum circuit-breaker or vacuum load switch 62, it is positioned at the top of the wall bushing 7 that is arranged on described ring main unit bottom, and the two ends of vacuum circuit-breaker or vacuum load switch 62 are connected with wall bushing 7 and insulated tension pole 4 respectively, is used for the switch divide-shut brake;
Be positioned at the gas tank 8 of described ring main unit bottom, it is that the stainless steel welding of 3MM is made by thickness, and switch main body parts are installed in it, is filled with dry gas or nitrogen, so that guarantee the insulation of switch and the corrosion resistance of whole mechanism.
Running of the present utility model is described below.
The utlity model has following beneficial effect:
The utility model forms vacuum environment by the suitable position at loop-network switch cabinet and reaches the arc extinguishing purpose.Adopt organic material and AIR MIXTURES as the external insulation medium simultaneously, therefore in the use of loop-network switch cabinet, can not cause murder by poisoning, more can not cause contaminated environment human body.
For the loop-network switch cabinet of traditional employing SF6 material, loop-network switch cabinet of the present utility model has reduced the high request to sealing, even gas leakage can not blasted yet; And can have anti-condensation, rainproof effect.
In this external loop networks switch cabinet of the present utility model; adopted the combination of vacuum circuit-breaker and vacuum load switch; therefore rated current and operation-current can be than traditional SF6 loop-network switch cabinet height, thereby can allow the capacity of protected transformer become bigger.
