Description

Low-voltage distribution equipment

Technical field

The utility model relates to a kind of controller switching equipment, relates in particular to a kind of low-voltage distribution equipment, belongs to field of electrical equipment.

Background technology

Controller switching equipment is very commonly used in people's production, life, need the zone of a large amount of electricity consumptions all must be equipped with power distribution equipment in a lot of factories, building site, large scale business district, office building, conference and exhibition center etc., the general volume of these power distribution equipments is larger, it is heavier to load, and the electric power scope of management is wide, management project is many.

Power distribution equipment is according to operational environment; can be divided into outdoor and indoor two kinds of situations; general indoor power distribution equipment is not exposed to wind and rain; operational environment is better; therefore stable performance; be not easy the generation problem, but be placed on outdoor power distribution equipment owing to be in external environment condition for a long time, along with environmental evolution; although be subject to the protection of shell; but under the long-term operating state, run into extreme case, rainwater can occur and pour into; dirt accumulation; impeded drainage causes the water storage phenomenon; thereby so that internal component makes moist; oxidation; the situations such as short circuit are inevitable, if untimely maintenance can be prone to accidents, can cause irretrievable loss under some occasion.

Simultaneously, present power distribution equipment on the market generally comprises block terminal, connecting line, shell, controls plate etc., needs for ventilation and heat, some power distribution equipment also disposes shutter, but these distribution boxs all are all Shortcomings of function singleness, fail safe and operability, not only can not satisfy growing equipment needs, but also can not provide more multi-functional.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of low-voltage distribution equipment, comprise outside cover plate and inner panel, described cover plate covers the panel outside, in panel, be provided with pilum, circuit breaker, switch, described pilum is distributed in each neutral gear place of panel, outer setting at cover plate has a plurality of insulator strings, on panel, also be provided with cooling system, circuit breaker is low-voltage circuit breaker, what be connected with circuit breaker has a post rod type A.C. contactor, and described post rod type A.C. contactor comprises push rod, node and coil.

Preferably, above-mentioned cooling system comprises shutter ventilation louver, ventilation hole and fin.

Preferably, above-mentioned shutter ventilation louver is arranged on the middle part of panel.

Preferably, above-mentioned ventilation hole has a plurality of, is arranged on the bottom of described panel, and ventilation hole is spaced apart side by side.

Preferably, the upper end of above-mentioned panel is provided with row's fin.

Preferably, also be provided with snap close in the above-mentioned panel.

The low-voltage distribution equipment that the utility model provides is by being arranged on low-voltage circuit breaker and the post rod type A.C. contactor in the power distribution equipment, after the Men Wei of power distribution equipment closes or opens, the push rod auto-returned, node disconnects, coil blackout is realized the safe power supply with electric loading.
