Specific embodiment

The utility model is further described with reference to the accompanying drawing.

As shown in figs 1 to 6, a kind of integral low pressure distribution box, including basement 1, feeder line room 2 and measure monitor room 3, Be separated between basement 1, feeder line room 2 and measure monitor room 3 using metal partion (metp), be equipped in basement 1 arrester 4, CT 5, knife-like switch 6 and incoming breaker 7 are measured, intelligent powerless compensation device 8,9 and of feeder breaker are installed in feeder line room 2 Outlet copper busbar 10 is equipped with metering electric energy meter 11, connection box of electric energy meter box 12 and Distribution transformer in measure monitor room 3 13.Distribution box basement 1,2 side of feeder line room are respectively arranged with the entrance hole 18 and outlet hole 19 of cable, and distribution box is using electricity Cable side goes out mode into side, and wire inlet/outlet hole uses rubber bound edge 20, and cabinet is equipped with radiator window 21 and condensation-preventing controller 22.

The cabinet basement 1 of distribution box and feeder line room 2 use back-to-back layout design, the copper bar of 7 lower end of incoming breaker After entering feeder line room 2 across metal partion (metp), leading-out wire copper busbar 10 or feeder breaker 9, the supporting element of various copper bars is equal Using insulator 23, and each copper bar exposed part is all made of insulating coating or heating Heat-Shrinkable Tubings processing, basement 1 and feedback Line room 2 is equipped with aperture and cabling channel to measure monitor room 3.The door of each warehouse is separately provided, and uses inside door 14 and external door 15 Design method, 14 panel of inside door be mainly arranged monitoring and operating element, fixed using hinge and set inside door 14 lock, 15 face of external door Viewing window, theftproof lock 16 and travel switch, inside door 14 and the equidirectional unlatching of external door 15 is mainly arranged in plate.The cabinet of distribution box is equipped with The louvered radiator window 21 of downward rain-proof, inside sets stainless steel Air Filter, and dust-proof mesh diameter should be not more than 1mm, the case of distribution box Temperature and Humidity Control and condensation-preventing controller 22 is arranged in body；The rubber of Anti-scratching is provided at long cable section of ingoing line hole 18 and outlet hole 19 Bound edge 20, rubber bound edge 20 has certain thickness, width, and has elasticity and toughness, can be to avoid scratch cable insulation.

The top of the box of distribution box is equipped with hoisting ring or lifting angle steel, bottom margin are uniformly arranged six fixed mounting holes.

Using adjustable electronic tripping distribution type breaker, Interruption is as follows for incoming breaker 7 and wire-outgoing breaker 9:

(1) thermal trip (overload long delay buckle releaser): at least meet adjustable in (0.75-1.5) In；
