Abstract
The utility model discloses a low-voltage cable branch box. The low-voltage cable branch box comprises a box body, a plurality of circuit breakers and a busbar which are installed in the box body and a disconnector, wherein the input end of the disconnector is connected with a connected cable, and the busbar is connected between the disconnector and the plurality of circuit breakers, so that the cable branch box is safe and reliable in use.
Description
Technical field
The utility model relates to a kind of low-voltage cable hut.
Background technology
Along with developing rapidly of State Grid's industry, cable hut is the power distribution equipment rapidly of a kind of development in recent years, it is widely used in outdoor AC three-phase 380V/220V, rated frequency 50Hz, rated current 800A and following low-voltage distribution electrical network, with cable to other user or devices allocation electric energy.Generally, multi-core controlled cable is used in the zone of concentrating from the control room to the field apparatus, and this multi-core controlled cable can connect on-the-spot cable hut, then is transferred to field apparatus from cable hut.Need not change at a distance cable like this when some core of certain root cable or cable goes wrong, process than being easier to.
The low-voltage cable hut that existing market occurs generally comprises the stainless steel casing, is arranged on the copper bus-bar in casing and a plurality of circuit breakers that are electrically connected mutually with copper bus-bar.Yet there is certain potential safety hazard in the mode that this copper bus-bar and circuit breaker directly are electrically connected mutually, especially when carrying out the circuit maintenance, can not be safer high pressure repair apparatus and charging equipment are disconnected.
The utility model content
The purpose of this utility model is for defects of the prior art, and a kind of novel low-voltage cable hut is provided, and it is safety and reliability in use.
For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme: a kind of low-voltage cable hut, comprise casing, be arranged on several circuit breakers and busbar in casing, it is characterized in that: described low-voltage cable hut also comprises isolating switch, the input of described isolating switch is connected with the access cable, and described busbar is connected between the output and described several circuit breakers of described isolating switch.
