Description

A kind of motor is powered switching wire casing

Technical field

This utility model belongs to a kind of switching wire casing, is specifically related to a kind of motor and powers switching wire casing.

Background technology

In some equipment electric power system, every machine is by connecting the corresponding with power supply wire casing for plug of machine stator Socket connects power supply, and multiple stage machine is shelved as an entirety and is powered by an independent wire casing, and existing situation is by two Platform converter band carries multiple stage machine startup and runs, an a-b box control converter and the power supply relation shelved, wire casing of powering Being an entirety with shelving, a-b box, converter and the distance between shelving are within 1 meter.

In unconventional test, owing to test exists certain danger, for ensureing the safety of personnel and equipment, need by Control line pass is to safety area, it is achieved remotely control.

In initial pilot system, when needs carry out this type of unconventional test, need to cut off all motor down-leads, Extend the motor energizing cables between machine and power supply wire casing, reappose motor according to test requirements document and power wire casing, and again Lay the connection line between power supply wire casing and a-b box, it is achieved the long-range control of circuit.But, in unconventional experiment and operation During the examination stage, again lay power supply wire casing and a-b box between connection line may cause lead short circuit, turnabout Deng accident potential, it is impossible to the personal safety of guarantee test personnel.

Utility model content

This utility model proposes to overcome shortcoming present in prior art, its objective is to provide a kind of motor Power supply switching wire casing.

The technical solution of the utility model is:

A kind of motor is powered switching wire casing, and described switching wire casing includes the box body with detachable top cover, above covers formation Many group plugs connect hole, and tray interior is transversely provided with the many groups of copper bar fixtures that be arranged in parallel, and copper bar fixture is by string four Size shape is identical and cross section is the fixed block composition of H type, is provided with perpendicular in the gap between two adjacent fixed blocks The copper bar that straight cutting enters.

Gap is there is between described often group copper bar fixture.

Gap is there is between the end of described adjacent copper bar.

The beneficial effects of the utility model are:

Application this utility model motor is powered switching wire casing, can quickly realize normally shelving to the unconventional circuit shelved Conversion, can be prevented effectively from and cut off motor down-lead, will not produce and cut off the various problems that occur of lead-in wire, and that improves supply line can By property, application motor switching wire casing, can carry out unconventional test at any safe distance simultaneously, it is to avoid sending out of personal injury Raw, facilitate testing crew to operate, meet system test requirement.

Detailed description of the invention

Carry out specifically below in conjunction with Figure of description and embodiment this utility model one motor powered switching wire casing Bright:

As shown in Fig. 1 ~ 3, a kind of motor is powered switching wire casing, and described switching wire casing 7 includes the box with detachable top cover 9 Body 8, upper cover 9 is formed many group plugs and connects hole 10, and box body 8 is internal is transversely provided with the many groups of copper bar fixtures 11 that be arranged in parallel, Copper bar fixture 11 is identical by four size shape of string and cross section is that the fixed block 13 of H type forms, and two adjacent fixing Gap between block 13 is provided with the copper bar 12 being inserted vertically into.

Gap is there is between described often group copper bar fixture 11.

Gap is there is between the end of described adjacent copper bar 12.

Using method of the present utility model:

As shown in Figure 4, the A phase of the A phase of converter 1, B phase, C phase and standby variable frequency device 2 in electric power system, B phase, C phase are equal It is connected with switching cabinet 3；The switching A phase of output of cabinet 3, B phase, C phase access in supply lines groove 4；Determine that special equipment is powered wire casing 4 Model, then by power supply wire casing 4 within three supply lines i.e. A phase, B phase, C phase segmentation, by connecting the most two-by-two Connecing, often group two set socket connects Work machine 6 and switching wire casing 7 by motor down-lead 5 respectively, it is achieved the extension of circuit controls； Lower section by two groups of switching back-to-back rotors being fixed on Work machine 6 of wire casing 7；It is accomplished by transferring wire casing 7 to work The rotor power-supply service of machine 6.
