Abstract
The utility model provides a wiring protection sleeve of a transformer, and relates to the technical field of electrical equipment. The wiring protection sleeve is mainly composed of a sleeve body and lock catches. The sleeve body is made of insulation thermochromic material. The appearance of an inner cavity of the sleeve body is matched with the appearance of a terminal of the transformer. A disc cover head is arranged at one end of the sleeve body. A wire inlet is formed in the side face of the sleeve body. An opening is longitudinally formed in the sleeve body. A lock side is outwards arranged on the longitudinal opening of the sleeve body. The lock side is connected through the lock catches. According to the wiring protection sleeve, the terminal of the transformer is sleeved with the sleeve body made of the thermochromic material, so that the influence of the outside on the terminal of the transformer is effectively reduced; the wiring protection sleeve can help power maintainers virtually inspect the temperature rise conditions of the terminal of the transformer, so that the power maintainers can find exceptions of a circuit in time, remove potential hazards in advance, and can greatly conveniently inspect and maintain electrical connecting points of the transformer, and safety of the power transformer is improved.
Description
Technical field
The present invention relates to electrical equipment technical field, be specifically related to a kind of Wiring protective sleeve for transformer.
Background technology
At present; the conducting position of power transformer terminals is exposed; in outdoor lower work, equipment and the damage to person accident that ionization burn into falling object from high altitude and external damage cause easily occurs, the current domestic device of effectively transformer wiring terminal being protected that also do not have mostly.
Summary of the invention
The invention provides a kind of Wiring protective sleeve for transformer, the transformer wiring terminal existed with the solution prior art lacks the problem of protective device.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of Wiring protective sleeve for transformer, mainly by body and snap close, formed, body is made by the insulation temperature-sensing color-changing material, the inner chamber of body and transformer wiring terminal profile are suitable, body one end arranges the disc capouch, and the cover body side surface arranges incoming line, and body vertically is provided with opening, the body longitudinal opening outwards is provided with lock seaming, and lock seaming connects by some snap closes.
Above-mentioned insulation temperature-sensing color-changing material has predetermined discoloring temperature scope, and when the cover temperature reaches described predetermined discoloring temperature scope, the insulation temperature-sensing color-changing material will variable color.
Above-mentioned insulation temperature-sensing color-changing material is heat discoloration silicon rubber.
Compared with the prior art, apparatus of the present invention are enclosed within on transformer wiring terminal by the body that temperature-sensing color-changing material is made, effectively reduced the impact of outer bound pair transformer wiring terminal, help the electric power maintenance personnel intuitively to make an inspection tour the temperature rise situation of transformer wiring terminal simultaneously, can find in time the abnormal of circuit, remove a hidden danger in possible trouble, greatly facilitate tour and the maintenance of electric power maintenance personnel to the transformer electric connecting point, the fail safe that has improved power transformer.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present utility model.
1 body, 2 capouch, 3 incoming lines, 4 lock seamings, 5 snap closes in figure.
Embodiment
Example 1
