It will be appreciated by those skilled in the art that the temp. controllable dust cap that the invention described above is proposed, various improvement and combination can also be made on the basis not departing from content of the present invention.Therefore, protection scope of the present invention should be determined by the content of appending claims.
Background technology
In existing casting technique, relate to a kind of circuit breaker, circuit breaker refer to the electric current that can close, carry and cut-off under normal loop condition and can close, the switching device of carrying and the electric current under cut-offfing abnormal loop condition in official hour.Circuit breaker can be used to distribute electric energy; infrequently start asynchronous motor; protection is carried out to power circuit and motor etc., can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And generally do not need to change parts after disjunction fault current.At present, obtain a wide range of applications.Circuit breaker is divided into primary cut-out by its scope of application, and low-voltage circuit breaker, and high-low pressure identification of boundaries is fuzzyyer, is called High-Voltage Electrical Appliances generally by more than 3kV.
The cut-off effect of high-voltage switch gear part to circuit breaker plays an important role, and especially in the middle part of casting process, allows any casting flaw, and the outward extending gusset of four direction also requires good weight capacity.In the prior art, due to the fault of construction of high-voltage switch gear part, cause the defective workmanship in casting process unavoidably, and surface roughness is low, needs follow-up polishing, greatly have impact on the efficiency of work, too increase and produce and artificial cost.
In view of this, should provide a kind of and meet novel high-voltage switch gear part, to solve the problems of the technologies described above.
Summary of the invention
The object of this invention is to provide a kind of surfacing, and interior tissue is not easy to loosen, meets the high-voltage switch gear part that casting requires.
In order to realize above-mentioned technical purpose, the invention provides a kind of high-voltage switch gear part, comprise switch member body, described Switch main body two ends are provided with connecting portion and support portion, described switch member body is provided with flange portion, described connecting portion is arranged on one end end face of described switch member body, and described connecting portion comprises the first groove and the second groove.
In some embodiments, described switch member body is cylindrical, and described flange portion is arranged on the cylinder of described switch member body.
In some embodiments, described first groove is positioned at end face center, described second groove is positioned at the side of described first groove, and the shape of described first groove is different from described second groove, and the size of described first groove is greater than the size of described second groove.
In some embodiments, described first groove is connected with circuit breaker with described second groove, and high-voltage switch gear part is engaged with circuit breaker.
