Abstract
The utility model discloses an outdoor-type neutral point earth resistance cabinet, which comprises a cabinet, a vent hole arranged at the top part of the cabinet and a closed crawl; and an inclined shielding cap is also arranged on the top surface of the cabinet. The neutral point earth resistance cabinet not only ensures that the neutral point earth resistance cabinet has better radiation performance, but also avoids rain water from flowing into the cabinet during the bad weather like typhoon, rainstorm and cyclone, which can cause an inside insulator to be broken down and shorted out, and can also cause unnecessary accidents like fire and creepage from happening. Meanwhile, the appearance of the entire cabinet is led to be more beautiful.
Description
Technical field:
The utility model relates to a kind of neutral resistance cabinet, particularly be a kind of neutral resistance cabinet of outdoor type.
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, the neutral resistance cabinet, and it comprises cabinet, with the ventilation hole that is located at the cabinet top, plays the effect of ventilation and heat; It is characterized in that the cabinet top is provided with closed fence, the top also is provided with a covering cap that tilts.When avoiding bad weather such as typhoon, heavy rain, cyclone by hiding cap, rainwater flows in the cabinet by air-permeating hole, causes the generation of insulant short circuit accident.
According to described neutral resistance cabinet, wherein, the base plate of above-mentioned cabinet has four bearings, by four whole cabinets of seat supports.
According to described neutral resistance cabinet, wherein, above-mentioned ventilation hole is grid-like ventilation hole and is provided with closed fence around it, avoids rainwater to flow in ventilation hole.
The utility model is provided with a covering cap that tilts at cabinet, guaranteed that not only the neutral resistance cabinet has better heat dispersion, and when bad weathers such as typhoon, heavy rain, cyclone, 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 another 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, the neutral resistance cabinet, it comprises cabinet 1, ventilation hole and bottom vents with being located at cabinet 1 top play the effect of ventilation and heat; Cabinet top periphery is provided with closed fence and by screw the one covering cap 2 that tilts is installed on the top board 12 of cabinet 1, this covering cap 2 is the rainproof baffle plate of an inclination, also can be for constituting to the rainproof baffle plate of the polylith that tilts all around, in the time of can avoiding bad weather such as typhoon, heavy rain, cyclone by hiding cap 2 and closed fence, 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 (as Fig. 2) such as neutral resistance device mounting hole and mounting groove are installed in cabinet, is convenient to install and use.
The utility model is equipped with the covering cap 2 and the closed fence 4 of inclination at cabinet 1, guaranteed that not only the 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.
