Abstract

The utility model relates to a row type terminal box structure for a low voltage high power motor, comprising a terminal box. The utility model is characterized in that: the terminal box is in a row type, a plurality of wiring terminals are provided to effectively divide large current; separation type wiring boards are provided; a vertical wiring copper bar is provided, the wiring boards are high low arranged; isolation board slots are provided; the wiring terminals are arranged on the separation type wiring boards in an upper row and a lower row, the isolation board slots are positioned at two sides of the separation type wiring boards; twelve wiring terminals of the motor are provided, four wiring terminals are provided for each phase; wiring boards are divided into two parts by the separation type wiring boards (2), and high low staggered in space position; the wiring copper bar is a vertical wiring copper bar, and the wiring boards are high low arranged. Verification is received in prototype trial-production, the capability of conducting large current of 1000A can be achieved, and technical requirements of the motor for conducting large current are fulfilled.

Description

Low-pressure high-power motor row's formula junction box structure

Technical field

The utility model relates to a kind of row's formula junction box structure of low-pressure high-power motor, belongs to technical field of motors.

Background technology

At present, the domestic one-tenth series of products that still do not have low voltage high-power threephase asynchronous motor (hereinafter to be referred as motor), wherein the motor of conducting electric current more than 1000A is one of technological difficulties with the terminal box design.

At present, prior motor is with in the terminal box design, because the electric current of institute's conducting is less, therefore also lower to the requirement that is electrically connected, for example binding post is 6; Motor lead is thinner etc.

The prior motor terminal box can not satisfy the big motor technology requirement of conducting electric current.

Summary of the invention

The purpose of this utility model is to provide a kind of row's formula junction box structure of low-pressure high-power motor, and this row's formula terminal box can be applicable to the motor of conducting electric current more than 1000A.

For achieving the above object, the technical solution of the utility model is: comprise that the motor binding post adopts 12, and 4 of every phases, the big electric current that will pass through is effectively shunted; The separate type terminal block is divided into two terminal block, and height staggers (connecting with copper busbar) on the locus; Design is vertical copper busbar in a zigzag.Arrange because terminal block is a height,, be convenient to terminal block in the space that below zigzag, forms so copper busbar is the zigzag structure; Design wiring division board draw-in groove.After terminal block is finished, be stuck in increase wiring safety in the draw-in groove with the wiring division board.

The beneficial effects of the utility model: be verified in the advanced development, can realize the ability of the big electric current of conducting 1000A, satisfy the big motor technology requirement of conducting electric current.

Description of drawings

Fig. 1 is the junction box structure figure of ordinary three-phase synchronous;

Fig. 2 (comprising Fig. 2 A, Fig. 2 B) is row's formula junction box structure figure of low-pressure high-power motor of the present utility model.

Embodiment

With reference to Fig. 1, this is the junction box structure figure of ordinary three-phase synchronous.

As shown in the figure, motor is with in the terminal box, because the electric current of institute's conducting is less, therefore also lower to the requirement that is electrically connected, binding post is 6; Motor lead is thinner.

With reference to Fig. 2 (comprising Fig. 2 A, Fig. 2 B), this is row's formula junction box structure figure of low-pressure high-power motor of the present utility model.

As shown in the figure, comprise that motor binding post (1) adopts 12,4 of every phases, the big electric current that will pass through is effectively shunted; Separate type terminal block (2) is divided into two terminal block, and height staggers (connecting with copper busbar) on the locus; Design vertical copper busbar (3) in a zigzag, arrange,, be convenient to terminal block in the space that below zigzag, forms so copper busbar is the zigzag structure because terminal block is a height; Design wiring division board draw-in groove (4) is stuck in increase wiring safety in the draw-in groove with the wiring division board after terminal block is finished.

Because the current of electric that the utility model is suitable for is very big; be generally about 1000A; because the lead wire of motor windings is thicker, adds the wiring position that will consider the various protective devices of motor windings, so terminal box is designed to the shape of " world is wide, the left and right sides is narrow ".

Though the utility model is described with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is used for illustrating the utility model; should understand and wherein can make variations and modifications and do not break away from the utility model in a broad sense; so be not that conduct is to qualification of the present utility model; as long as in connotation scope of the present utility model, to the variation of above-described embodiment, the protection range that distortion all will fall into the utility model claim.

Claims

1. a low-pressure high-power motor comprises a terminal box with row's formula junction box structure, and it is characterized in that: described terminal box is row's formula, effectively shunts for big electric current, and binding post has a plurality of; The separate type terminal block; Vertical copper busbar, terminal block are that height is arranged; The division board draw-in groove is arranged; Binding post divides two rows to be arranged on the separate type terminal block, and the division board draw-in groove is positioned at separate type terminal block both sides.

2. row's formula junction box structure as claimed in claim 1 is characterized in that: described motor binding post (1), adopt 12,4 of every phases.
