Description

A kind of rainproof distribution box
Technical field
The invention belongs to controller switching equipment technical field, relate to a kind of rainproof distribution box.
Background technology
Distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment.Can connect or point deenergizing by manual or automatic switch during normal operation.Circuit or warning is cut off by protective device when fault or irregular operating.Distribution box is one of power supply facilities the most basic in urban construction.At present, distribution box is primarily of casing and internal component composition.But after permanent use, easily heat is too high causes short circuit accident for present distribution box, and present distribution box cannot avoid problems.For this reason, we provide the good distribution box of a kind of air permeability very necessary.
Through retrieval, as Chinese invention patent application (application number: 201210277545.8) disclose a kind of ventilation distribution box, comprise casing, at bottom half and the back side, a S shape square opening ventilator is installed, the end mouth of described ventilator is arranged on bottom half, the back side of casing is close in the stage casing of ventilator, the reverse position of outlet at casing top of ventilator; Open-work is offered on the surface being close to box back surface in ventilator stage casing.The present invention has the advantages such as rational in infrastructure, convenient and practical, safe and reliable.But the water resistance of this invention is poor, once distribution box enters the water capacity easily produce electric leakage or circut breaking, easily causes security incident when distribution box leaks electricity.
