Abstract
The unit of low-volatile distribution cabinet includes left and right side plates with double-folded edge, fixed plate, removable back plate, and installation beams being connected. Advantages are: under precondition of not changing original outline structure of unit in draw-out type to reach purpose of operation without opening door. In procedure of operation, function for displaying position requested by national standard is satisfied. Technique of double-folded edge enhances intensity. Thus, thickness of plate is changed to 1.0-1.5mm, and more than 1/4 cold steel plate is saved. Electrical connector pieces on moved plate are still aligned to vertical bus precisely. Both way connector (BC) is in module form. Being connected to BC, the conducting strip is changed to forficiform structure from thermal fin type. Thickness of copper plate changes to 2.0mm so as to save material, but still meet requirement of contact insertion and withdraw force, and standard value of temperature rise.
Description
Technical field
What the present invention relates to is a kind of low-voltage distribution cabinet (MCC) not-opening door operation tapping unit, belongs to low pressure pull-out type switchgear assembly technical field.
Background technology
The tapping unit position operation overwhelming majority is carried out for mobile drawer body in the existing low pressure pull-out type switchgear assembly, its electric connection point contact is unbalanced, and the contact contact resistance is big, temperature rise, and tapping unit shifts out in the process in the position, and degree of protection is not easy to guarantee.Be difficult to satisfy the requirement of engineering of requirement of low-pressure system high-protection level and special dimension use.The technology that a kind of not mobile drawer body is arranged in the prior art, as patent of invention (ZL200410064770.9), its denomination of invention is: a kind of movable propelling continuous drawer function unit, its structure is to have functional unit base, functional unit base is provided with movable part and propulsive mechanism, also be provided with the chain release mechanism in position on the functional unit base, propulsive mechanism is fixedlyed connected with movable part, be installed with the stationary part of movable plug-in unit on the functional unit base, be installed with the movable part of movable plug-in unit on the movable part, propulsive mechanism promotes movable part and moves forward and backward in functional unit, movable plug-in unit can be realized and vertical bus, separate between quiet plug-in unit of main circuit and the quiet plug-in unit of auxiliary circuit, three kinds of test and connection are electrically connected state, when movable part moves to test or link position, the chain release mechanism in position automatically locks propulsive mechanism, movable part can not move, have only the chain release mechanism release in manual operation position, propulsive mechanism could continue to promote movable part.Its defective is that regular screw threads screw rod rotating distance is long, operating physical force is big, the sheet-metal member of move operation part, location, guiding all need high accuracy, complex structure, it can only be installed and used on special rack that cooperates for it in addition, has put upside down the relation of main component and adapted member, gives to apply and has brought inconvenience.It is the sheet closed assembly as being electrically connected the input/output port electric connecting sheet that movable part uses, and does not have heat-dissipating space between laminated structure and two, has influenced ampacity.
Summary of the invention
Purpose of the present invention is intended to overcome the defective of above-mentioned existence, proposes low-voltage cabinet not-opening door operation tapping unit a kind of simple in structure, easy for operation, with low cost.
Technical solution of the present invention: it is characterized in that by the left side plate after the processes of two-fold limit, install main circuit turnover line plug fixed head, mobile back plate, the base plate of main circuit input/output port and auxiliary circuit plug has been installed and install transmission mechanism and position locking mechanism mounting rail and preceding go up the back down mounting rail be formed by connecting.
Advantage of the present invention: not-opening door operation tapping unit has reached the purpose of not-opening door operation under the prerequisite that does not change former each model low-voltage distribution cabinet tapping unit contour structures.The function that obvious connection, test, isolation three position display are arranged that can satisfy among the GB7251.1 in the operating process to be proposed.Two-fold limit form is adopted in the main sheet metal structural spare design of not-opening door operation tapping unit, and metal plate material thickness changes 1.0～1.5mm into by former 2.0mm, and intensity increases, and cold steel metal plate material is saved more than 1/4.The spacing in the same way slip in many places of tapping unit not-opening door operation mechanism, particularly dovetail groove type detent mechanism that slides synchronously with drive lead screw and balance plate can guarantee to move the main and auxiliary circuit connector and the accurate contraposition of vertical bus of installing on the plate of back, reduced the required assembly precision requirement of tapping unit not-opening door operation, screw mandrel is a trapezoidal thread, has shortened operational stroke.The electrical connection input/output port that install the tapping unit rear end is modularized design, can be according to different current value combine and assemble.To satisfy the requirement of different current classes such as 100A, 250A, 400A, 630A.The conducting strip that is used in the input/output port patch changes fin scissors fork structure into by former flat closed assembly structure, leave the heat radiation gap between two, used copper metal plate material changes 2.0mm into by former thick 2.5mm, has satisfied contact engaging and separating force simultaneously and the temperature rise standard value is no more than the requirement of 55K, and has saved coloured
The consumption of metallic copper metal plate material.
