Abstract
A low voltage power distribution cabinet with good heat radiation belongs to the technical field of low voltage electrical apparatuses, which aims to improve the ventilating and heat radiating effects of the power distribution cabinet and improve the running reliability of the electrical apparatuses. The technical scheme is that the low voltage power distribution cabinet comprises a cabinet body, electrical apparatus drawers, spacer boards and a plug-in component fixing board; a heat radiating air passage is arranged between a side board at one side of the cabinet body and the electrical apparatus drawers; a side wall of the heat radiating air passage is separated from the electrical apparatus drawers; the side wall of the heat radiating air passage is provided with a plurality of air outlets; the air outlets respectively correspond to the electrical apparatus drawers; an exhausting fan is arranged at each air outlet. Hot air in the electrical apparatus drawers is compulsively exhausted by the exhausting fans through the heat radiating air passage; the exhausting fans play a role of quickly reducing the temperature of the power distribution cabinet. The ventilating and heat radiating effects of the power distribution cabinet are obviously improved; the malfunction of an electrical apparatus protective circuit is greatly reduced; the service life of the electrical apparatuses is prolonged; and the running reliability of the electrical apparatuses is improved.
Description
Technical field
The utility model relates to a kind of low-voltage distribution cabinet, belongs to the low voltage electrical equipment technical field.
Background technology
At present, the ventilation of traditional low-voltage distribution cabinet is that the grid on employing low-voltage cabinet top enters the natural gap between exhaust outlet, electrical equipment drawer and the cabinet left and right sides side plate, and the grid of the interlayer board between electrical equipment drawer and the electrical equipment drawer ventilates.Ventilation effect is poor, easily causes the misoperation in electric prospection loop, makes electric device low useful life, influences the reliability of electric equipment operation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of result of ventilating heat dissipation that can obviously improve power distribution cabinet; reduce the misoperation in electric prospection loop greatly; prolong the useful life of electric device, improve the good low-voltage distribution cabinet of heat radiation of electric equipment operation reliability.
The technical scheme that solves the problems of the technologies described above is:
A kind of good low-voltage distribution cabinet that dispels the heat, it comprises cabinet, electrical equipment drawer, interlayer board, plug-in unit fixed head, the electrical equipment drawer has a plurality of, be arranged above and below in cabinet, its improvements are, increasing between the side plate of cabinet one side and electrical equipment drawer has heat dissipation wind channel, heat dissipation wind channel sidewall and electrical equipment drawer are isolated, a plurality of exhaust outlets are arranged on the heat dissipation wind channel sidewall, and each exhaust outlet is corresponding with the electrical equipment drawer respectively, at each exhaust outlet place ventilating fan is installed.
The low-voltage distribution cabinet that above-mentioned heat radiation is good has the air intake grid on the plug-in unit fixed head.
The low-voltage distribution cabinet that above-mentioned heat radiation is good, rear cabinet door the first half of cabinet has the air intake grid, and metal screen is installed on the grid.
The low-voltage distribution cabinet that above-mentioned heat radiation is good, described ventilating fan has attemperating unit.
Low-voltage distribution cabinet is through after the above-mentioned improvement, ventilating fan is forced the hot blast in the electrical equipment drawer to discharge by heat dissipation wind channel, thermostat starts ventilating fan automatically according to design temperature, play the effect of quick reduction power distribution cabinet temperature, the air intake grid of plug-in unit fixed head and rear cabinet door can be accelerated the circulation of air, help the discharge of hot blast, also can promote the cooling of low-voltage distribution cabinet.The utility model obviously improves the result of ventilating heat dissipation of having joined electric cabinet, greatly reduces the misoperation in electric prospection loop, has prolonged the useful life of electric device, has improved the electric equipment operation reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a plug-in unit fixed head schematic diagram of the present utility model;
Fig. 3 is a rear cabinet door schematic diagram of the present utility model.
Mark is as follows among the figure: cabinet 1, heat dissipation wind channel 2, heat dissipation wind channel sidewall 3, ventilating fan 4, interlayer board 5, plug-in unit fixed head 6, plug-in unit fixing hole 7, rear cabinet door 8, grid 9.
Embodiment
