Abstract

The utility model discloses a thin-type 1/2 unit drawer line distribution switch. The switch is characterized in that: two main circuit wire inlet sockets and main circuit wire outlet sockets are arranged at the front-lower part inside a metal shell body; two wire inlet auxiliary circuit sockets are arranged at the front upper part in the metal shell body; a monopole power supply wire inlet plug is arranged at one side of the reverse side, and a terminator clamping plate is arranged at the other side; cable wire outlet grooves are arranged between the terminator clamping plate and the auxiliary circuit wire outlet sockets; the main circuit wire inlet sockets, the monopole power supply wire inlet plug and the main circuit wire outlet sockets are connected with a current terminator by main circuit connecting cables; and the wire inlet auxiliary circuit sockets are connected with the auxiliary circuit wire outlet sockets by auxiliary circuit connecting wires. The switch has the advantage: the structure is simple; the main circuit wire outlet sockets are replaced by the current terminators, so as to enlarge the cable space in the metal shell body; and the depth of a 1/2 unit drawer can be increased. A primary main circuit outlet line is connected with the current terminators, which is visual and reliable, and can be conveniently changed according to phase distance and numbers of vertical buses.

Description

Thin type 1/2 unit drawer lane assignment adapter

Technical field

The utility model proposes a kind of thin type 1/2 unit drawer lane assignment adapter that is applicable to back outlet and side outlet in the low pressure pull-out type switchgear assembly MCC cabinet.Lane assignment switching usefulness when it can be two 1/2 unit of 63A～100A drawer as MCC cabinet individual layer installation electric current, the design and fabrication technology field of the dedicated devices that uses in the genus low pressure pull-out type switchgear assembly.

Background technology

The 1/2 unit drawer lane assignment adapter that uses in the prior art, because installing device is many in the housing, one time the line difficulty is caused in stube cable line cross section greatly, so it takies the interior deep space of cabinet big (outer casing thickness size＞85), has directly reduced the depth dimensions of drawer thus.But 1/2 unit drawer as electronic control centre uses needs certain space at switch rear portion installation elements and line, has shortened depth dimensions, must bring the difficulty of element installation and line.Moreover electric current is the lane assignment adapter of 100A, an outlet seat is to be directly installed in the housing, can't cabling after the corresponding increase of need adopting in cable cross section, can only connect by the insulating part winding displacement with little copper busbar, therefore be the lane assignment adaptor of 100A for electric current, since the requirement of electric insulation distance, the structure more complicated, the device component part is also many, the also corresponding increase of cost.

Summary of the invention

The utility model is intended to overcome above-mentioned defective, propose a kind ofly link allocater to be changed thin (＜70), again can ease of assembly, can also be convenient to use the cable wiring at electric current during for 100A, and can by instructions for use change at a distance of and determine a kind of new thin type 1/2 unit drawer lane assignment adapter of the number of phases (A, B, C mutually or A, B, C, N phase).

Technical solution of the present utility model: it is characterized in that in the front lower place of the metal shell of adapter and drawer abutted surface 2 main circuit leading-in sockets and 2 main circuit output sockets being installed, the top is equipped with 2 inlet wire auxiliary circuit sockets; Its back side one side on request the number of phases and unipolar power source inlet wire plug apart is installed, opposite side is equipped with confesses the terminal clamp that the line current terminal is installed usefulness, between terminal clamp and auxiliary circuit outlet seat, have the cable outlet groove, between main circuit leading-in socket and unipolar power source inlet wire plug and main circuit output socket and current terminal, use the main circuit stube cable that is complementary with electric current to be connected, between inlet wire auxiliary circuit socket and auxiliary circuit outlet seat, be connected by the auxiliary circuit connecting line.

Advantage of the present utility model: simple in structure, former two main circuit outlet seats that are contained in the metal-back have been saved, main circuit outlet seat is substituted by current terminal, increased the cable routing space in the metal shell like this, thereby the thickness that makes the virgin metal housing by＞85 be reduced to＜70, the depth dimensions of 1/2 unit drawer can be deepened thus.Space and wiring space that original paper is installed in the 1/2 unit drawer all are improved.A main circuit outlet is connected with current terminal, intuitive and reliable, once pass in and out line end and can require install 3 mutually or 4 pass in and out line socket mutually according to the number of phases, the single step arrangement electric power incoming line plug that is connected with vertical bus can be easily according to vertical bus apart and the number of phases change.The side of metal shell is suppressed with knock down hole, can install for the side outlet.
