A kind of safety type distribution box
The utility model relates to a kind of distribution box, is specially a kind of safety type distribution box.
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.Operating various parameter can be shown by means of measuring instrument, also can adjust some electric parameter, point out departing from normal operating conditions or send signal.Be usually used in each, join, in electric substation.
Can with high voltage or high electric current in distribution box, work is easy to produce heat for a long time, and may occur leakage of electricity, leaky, and people are difficult to find, can not get processing timely causing more serious consequence.When distribution box is arranged on the larger place of humidity, inner electric appliance component is easy to electric leakage.
