Abstract
The utility model discloses a neutral point grounding resistor cabinet body, which comprises a cabinet body. The utility model is characterized in that vent holes are arranged on the peripheral side walls and on the top of the cabinet body, the periphery of the vent holes on the top of the cabinet body is provided with a sealed type rail, and the upper part of the sealed type rail is also provided with a shielding cover cap. The utility model ensures better heat radiation performance of the neutral point grounding resistor cabinet body, in addition, rain is prevented from flowing into the cabinet body to cause internal insulator puncture short circuit in rainy weather, and the occurrence of unnecessary accidents such as fire hazard, electric leakage and the like can be avoided. At the same time, the appearance of the whole cabinet body is more artistic.
Description
Technical field:
The utility model relates to a kind of neutral resistance cabinet, particularly be a kind of neutral ground cabinet.
Background technology:
In recent years, along with developing rapidly of China's power industry, the structural change of urban power distribution network is very big, and the neutral resistance cabinet also more and more is applied in the urban power distribution network.And the neutral resistance cabinet is mainly used in connecting of main transformer neutral point and ground network in the power distribution network of town and country, and the town and country power distribution network mainly refers to the electrical network of 10kV, 35kV, three electric pressures of 66kV, has a large capacity and a wide range in electric power system, occupies an important position.Along with the deep development of urban network restructuring, 10KV power distribution network capacity increases sharply, and network configuration is gradually improved, and according to the urban construction needs, outdoor type neutral resistance cabinet also widespread in the power distribution network of town and country.
At present, the neutral resistance cabinet that uses is for guaranteeing to have better heat dispersion, adopted venetian blind type around the cabinet, this have a good internal heat dissipating function, but when rainy weather, rainwater flows into inside easily, thereby causes the internal insulator puncture short, causes unnecessary accident to take place.
The utility model content:
The utility model purpose provides a kind of neutral resistance cabinet with good rainproof and heat sinking function, is used for remedying the deficiencies in the prior art.
To achieve these goals, the technical solution of the utility model is, a kind of neutral resistance cabinet, and it comprises cabinet, it is characterized in that, sidewall and top are provided with air-permeating hole around the described cabinet, play the effect of ventilative heat radiation; Be provided with closed fence around the air-permeating hole of described cabinet top, be provided with one on fence top and hide cap, when avoiding rainy weather by hiding cap, rainwater flows in the cabinet by air-permeating hole, causes the generation of insulant short circuit accident.
According to described a kind of neutral resistance cabinet, wherein, the base plate of above-mentioned cabinet has four bearings, by four whole cabinets of seat supports.
According to described a kind of neutral resistance cabinet, wherein, above-mentioned air-permeating hole is grid-like air-permeating hole.
The utility model is provided with one at cabinet and hides cap, guaranteed that not only a kind of neutral resistance cabinet has better heat dispersion, and when rainy weather, avoided rainwater to flow in the cabinet, cause the internal insulator puncture short, cause unnecessary accident such as fire, electric leakage to take place.Simultaneously, make whole cabinet profile more attractive in appearance.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an embodiment front view of the present utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to figure 1, a kind of neutral resistance cabinet, it comprises cabinet 1, and is located at the air-permeating hole 11 on the sidewall and top around the cabinet 1, plays the effect of ventilative heat radiation; This cabinet 1 is that the number of metal sheet is formed by connecting by screw or rivet, and all is shaped on air-permeating hole 11 respectively on six walls of cabinet 1, and this air-permeating hole 11 can be the neat rectangular opening of some row examples, circular port, shape hole such as tri-angle-holed; In order better to let in air and rainproof function, this air-permeating hole adopts grid-like air-permeating hole, can adopt rectangular opening or circular port etc. on the base plate of cabinet, and the liquid of being convenient to flow into accidentally in the cabinet 1 flows out.On the top board 12 of cabinet 1, the one covering cap 2 that tilts is installed by screw, this covering cap 2 is the rainproof baffle plate that tilts, also can for to around the rainproof baffle plate of polylith that tilts constitute, when avoiding rainy weather by hiding cap 2, rainwater flows in the cabinet 1, causes the generation of insulant short circuit accident.Under the base plate of cabinet 1, by four bearings 3 of screw,, also can fix the bearing 3 more than six or six in cabinet 1 bottom, support whole cabinet by bearing 3 for guaranteeing the stability of cabinet.
In addition, according to different needs, cabinet 1 inner neutral resistance device mounting means difference is shaped on groove positions 4 such as neutral resistance device mounting hole and mounting groove are installed in cabinet, is convenient to install and use.
The utility model is provided with closed fence all around at cabinet 1 top, the covering cap 2 of inclination is installed on fence top, instrument has not guaranteed that a kind of neutral resistance cabinet has better heat dispersion, and when rainy weather, avoid rainwater to flow in the cabinet 1, cause the internal insulator puncture short, cause unnecessary accident such as fire, electric leakage to take place, simultaneously, make whole cabinet 1 profile more attractive in appearance.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
