Abstract
The utility model discloses a construction site distribution box, including the box and install in the box total circuit breaker with divide the circuit breaker, total circuit breaker meets inlet circuit through generating line and insulator, total circuit breaker with divide the circuit breaker to pass through insulated wire to be connected, total circuit breaker is equipped with cover plate and lower cover plate with dividing the circuit breaker outside, the side of upper and lower cover plate is connected respectively on the box curb girder, the reservation has total circuit breaker, branch circuit breaker handle hole on last cover plate and lower cover plate. Hide shelves through install the glass cover plate additional to construction site distribution box exposed conductive part to reserve the handle hole that has air circuit breaker on the organic glass board, can avoid the electrically conductive position emergence electric shock of switch wiring department in the block terminal dangerous, guarantee operator's personal safety, visible isolation, overload, short circuit and the electric leakage protection function who divides the breakpoint have to have auto -power -off protect function under the auxiliary electrical power source trouble condition, circuit breaker switch contact's disconnection -connection states is directly perceived visual, more conveniently manipulates.
Description
Technical field
This utility model relates to the controller switching equipment of power industry, particularly a kind of building site distribution box.
Background technology
Distribution box local in actual use in building site there is also some defects at present, is configured to a total air-break, at total air-break to divide into several branch circuit breakers in usual distribution box.Copper core insulated conductor is used to connect in distribution box, wire branch joint uses bolt crimping, there is exposed conductive part, the most in use, exposed part is had at switch wire connection in distribution box, if misoperation or the least mistiming touch exposed conductive part, and Danger Electric shock risk all can occur, leave great potential safety hazard.And the air-break in the distribution box of tradition building site typically uses common breaker of plastic casing, contact deciliter state is invisible from outside.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art to exist, it is provided that the building site distribution box that a kind of operation more conveniently, safely uses.
This utility model solves technical problem and the technical scheme is that a kind of building site distribution box, including the main breaker in casing and installation casing and a point chopper, main breaker connects inlet circuit by incoming-line busbar and supports insulative, main breaker is connected by insulated conductor with a point chopper, it is characterized in that: equipped with upper cover plate and lower cover plate outside described main breaker and point chopper, the side of upper and lower cover plate is connected on casing curb girder；Upper cover plate with lower cover plate are reserved with main breaker, the handle hole of point chopper.
Described upper cover plate is made by poly (methyl methacrylate) plate with lower cover plate.
Described main breaker installs the transparent plastic shell of visual cut-off point with point chopper.
The incoming-line busbar and supports insulative that connect main breaker are positioned at upper cover plate top behind.
This utility model carries out shield by building site distribution box exposed conductive part is installed additional glass hood plate, and on poly (methyl methacrylate) plate, it is reserved with the handle hole of air-break, so can avoid conducting position generation Danger Electric shock risk at the switch wire connection in distribution box, improve the safety of product, it is ensured that the personal safety of operator；Use transparent outer cover; having the isolation of visible breakpoint, overload, short circuit and a creepage protection function, and have under accessory power supply failure condition and automatically power off defencive function, deciliter state of killer switch contact is the most visual; its compact conformation, energy-conservation, safe and reliable, convenient operate with.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is the side view of Fig. 1.
In figure: 1 casing；2 main breakers；3 points of choppers；4 upper cover plates；5 times cover plates；6 handle holes；
7 insulated conductors；8 curb girders；9 door lock Rainproof cases；10 door hinges；11 supports insulative；12 incoming-line busbars.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the building site distribution box designed by this utility model is primarily adapted for use in rated voltage exchange 380V/220V, rated frequency 50Hz, rated current 400A-32A, specified limit make-break capacity: 10kA, rated residual operating current I △ n 30mA.Specified electric leakage movement time≤0.1s(consumer unit requires to provide delay protection according to user) there is overload, short circuit, creepage protection function.This building site distribution box, including the main breaker 2 in casing 1 and installation casing and a point chopper 3, casing 1 installs chamber door, equipped with door lock and door lock Rainproof case 9 outside chamber door by the door hinge 10 of sidepiece；Being positioned at the inlet circuit outside casing upper support insulator 11 1 termination casing, the other end connects incoming-line busbar 12, and incoming-line busbar connects main breaker 2, and main breaker is connected by insulated conductor 7 with a point chopper；Equipped with upper cover plate 4 and lower cover plate 5 outside main breaker and point chopper, the side of upper and lower cover plate is connected on the curb girder 8 of casing 1；Being reserved with main breaker handle hole 6 at upper cover plate 4, lower cover plate 5 leaves each point of chopper handle hole 6, and the incoming-line busbar 12 and supports insulative 11 that connect main breaker 2 are positioned at upper cover plate 4 top behind.The most neither affect the normal operating of air-break, but also can guarantee that people is not readily accessible to the exposed conductive part of air-break when operation, to prevent electric shock accidents from occurring.Upper cover plate 4 makes by poly (methyl methacrylate) plate with lower cover plate 5, so can avoid conducting position generation Danger Electric shock risk at the switch wire connection in distribution box, it is ensured that operator's personal safety；Main breaker 2 all installs the transparent plastic shell of visual cut-off point with point chopper 3; there is the isolation of visible breakpoint, overload, short circuit and creepage protection function; and have under accessory power supply failure condition and automatically power off defencive function; deciliter state making chopper position switch contact is intuitively visual, be more convenient for safety operation and use.
