Technical field

This utility model belongs to generator excitation bus polarity switching technical field, particularly to a kind of novel excitation bus Polarity switched devices.

Background technology

Excitation bus: provide exciting current for generator amature, this bus is red copper, conducts electricity very well, positioned at electromotor And field regulator between.There is slip ring galvano-cautery problem in power generator at present, for preventing slip ring galvano-cautery from damaging slip ring, Ask 1-4 to carry out a polarity reversal, to reduce slip ring galvano-cautery, extend the service life of slip ring, but often secondary to bus Carry out overall pulling down replacing to bother very much, excitation bus polarity reversal is difficult, dumb, uneconomical, and workload is very big, dismounting Affect the excitation property of energized circuit contact resistance and electromotor more than position again.

Content of the invention

The purpose of this utility model is to provide a kind of novel excitation bus polarity switched devices, this switching device structure letter Single, manufacture simple installation, it is to avoid the dismounting to excitation bus shifts during excitation bus polarity reversal, polarity reversal side Just, flexibly, fast, there is high use value.

The purpose of this utility model is achieved in that a kind of novel excitation bus polarity switched devices, including insulation board, Binding post, switching wire, described insulation board arrange four binding posts, described binding post is arranged side by side two-by-two, described Binding post overall structure is the cylindrical binding post of the type of falling l, and the lower end of described binding post is female with excitation bus a, excitation respectively Line b, degaussing switch electrode line, degaussing switch negative line are fixedly connected, and the upper end of described binding post connects switching wire, described Binding post and excitation bus a, excitation bus b, degaussing switch electrode line, degaussing switch negative line, switching wire between connecing Synapsis is both configured to semicylinder structure.

Described binding post, excitation bus a, excitation bus b, degaussing switch electrode line, degaussing switch negative line, switching are led The radius of line is identical.

Connection between described binding post and each wire is insulated fastener fitted bolt and is connected.

The internal diameter of described insulated fastener is identical with the external diameter of binding post.

Described binding post makes for red copper.

The outside of described switching wire is provided with insulating barrier.

The beneficial effect that this utility model produces is:

1st, this utility model is arranged between automatic excitation adjustor of generator and degaussing switch, when carrying out dipole inversion, only Need to carry out shifting by the switching wire between binding post, it is to avoid the dismounting of the excitation bus at open position two ends moves Excitation bus, it is ensured that polarity switching fast and flexible is carried out, will not be damaged in position again.

2nd, this utility model is both configured to semicylinder by binding post and the positive and negative line contacts of excitation bus, degaussing switch Structure, that is, increased contact area, is easy to be securely fixed with insulated fastener again.

3rd, the outside setting insulating barrier of switching wire, it is to avoid cross occurrence short circuit phenomenon after switching wire displacement.

Specific embodiment

Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.

Embodiment 1

As shown in accompanying drawing 1-8, a kind of novel excitation bus polarity switched devices, lead including insulation board 1, binding post 2, switching Line 3, described insulation board 1 arranges four binding posts 2, and described binding post 2 is arranged side by side two-by-two, and described binding post 2 is whole Body structure is the cylindrical binding post of the type of falling l, the lower end of described binding post 2 respectively with excitation bus a4, excitation bus b5, go out Magnetic switch electrode line 6, degaussing switch negative line 7 are fixedly connected, and the upper end of described binding post 2 connects switching wire 3, described Between binding post and excitation bus a4, excitation bus b5, degaussing switch electrode line 6, degaussing switch negative line 7, switching wire 3 Contact position is both configured to semicylinder structure.

Described binding post 2, excitation bus a4, excitation bus b5, degaussing switch electrode line 6, degaussing switch negative line 7, The radius of switching wire 3 is identical.

Connection between described binding post 2 and each wire is insulated fastener 8 fitted bolt 9 and is connected.

The described internal diameter of insulated fastener 8 is identical with the external diameter of binding post 2.

Described binding post 2 makes for red copper.

The outside of described switching wire 3 is provided with insulating barrier.

This utility model is when using: a kind of novel excitation bus polarity switched devices, including insulation board, binding post, cuts Change wire, four and wiring column diameter identical circular hole are arranged side by side on insulation board, binding post are installed on the circle of insulation board Certain length is all exposed in hole it is ensured that both sides, and binding post is fixed.Then, degaussing switch is exported to excitation busbar In the middle of place, 1 meter about of excision, this device is installed on herein, excitation bus a and excitation bus b two wiring with bottom respectively The lower end of post contacts relatively, then clasps blending bolt with insulated fastener and tightens；Degaussing switch positive pole, negative line be aligned top two The lower end of individual binding post, then clasps blending bolt with insulated fastener and tightens.Finally, the two ends of switching wire respectively and are connected The upper end insulated fastener of the binding post of excitation bus a and degaussing switch electrode line clasps, and blending bolt is tightened；Another is cut The two ends changing wire clasp with the upper end insulated fastener of excitation bus b and the binding post of degaussing switch negative line respectively, are used in combination Bolt is tightened, and now excitation bus and degaussing switch have been deformed into a complete loop.When needing to carry out dipole inversion, only need The bolt of the insulated fastener of fixing switching wire one end is backed out, then borrows switching wire to another relative binding post On, that is, complete dipole inversion, this process does not need excitation bus to be carried out remove displacement, convenient, flexible, saving manpower, section About pay wages.

Generally, during this utility model ensures polarity switching, it is to avoid excitation bus is carried out remove displacement, make generating Machine excitation bus fall polar operation more flexibly, convenient, save manpower, cut down expenses.
