Abstract
The utility model provides a telescopic ice -melt short circuit switch of level with lightning protection function, including the three support that sets gradually, the upper end of three support is respectively along the vertical arrester that is provided with, and arrester upper end on two supports in both sides is fixed respectively to be provided with a telescopic switch of level, is provided with switch contact fishplate bar on the arrester of center support's upper end, when two telescopic switchs of level stretch out, the contact of two telescopic switchs of level end respectively with switch contact fishplate bar electrical connection, two telescopic switchs of level are connected with electronic actuating mechanism respectively. In order to solve current terminal three phase line short circuit, need increase the short circuit switch in addition, increased area, under the not enough condition in transformer substation place, still need take over the land for use again, increased the construction investment to the construction period scheduling problem of engineering has been prolonged. The utility model belongs to circuit ice -melt field.
Description
Technical field
The utility model relates to a kind of ice-melt short circuit disconnecting link, belongs to line ice-melting technical field.
Background technology
Ice damage is the large technical barrier that electric power system industrial quarters does one's utmost to tackle always.In recent years, along with the change of global climate condition, low temperature sleet and snow ice weather frequently occurs in south China, Central China and North China, repeatedly causes each province of China transmission line large area, stops transport for a long time, bring about great losses to national economy and people's lives.In order to prevent the generation of this type of accident, China actively develops the research of transmission line de-icing technology, have developed DC de-icing device, and is progressively applied in China's grid power transmission circuit.Use DC de-icing device when carrying out ice-melt, need short circuit DC ice-melting, the method for short circuit circuit is mainly by artificial short circuit with install ice-melt Special short disconnecting link additional before.The former length consuming time, and operation intensity is large, operating risk is high; The latter, due to the newly-increased one group of disconnecting link of needs, adds occupation of land face, some old transformer stations or the transformer station that is positioned at down town due to place limited; enough positions are not had to increase disconnecting link newly; usually also need again to take over the land for use, not only increase construction investment, and extend the construction period of engineering.
Summary of the invention
The purpose of this utility model is: provide a kind of horizontal retractable ice-melt short circuit disconnecting link with lightning protection function, replacing is transformed in former outlet lightning arrester position, to solve existing end three-phase line short circuit, need to increase short circuit disconnecting link in addition, add floor space, when the space is insufficient in transformer station, also need again to take over the land for use, add construction investment, and extend the problems such as the construction period of engineering.
Scheme of the present utility model is as follows: a kind of horizontal retractable ice-melt short circuit disconnecting link with lightning protection function, comprise three supports set gradually, the upper end of three supports is vertically provided with lightning arrester respectively, the upper end of the lightning arrester on the support of two, both sides is fixedly installed a horizontal retractable disconnecting link respectively, the lightning arrester of intermediate support upper end is provided with disconnecting link contact fishplate bar, when two horizontal retractable disconnecting links trail, the contact end of two horizontal retractable disconnecting links is electrically connected with disconnecting link contact fishplate bar respectively, two horizontal retractable disconnecting links are connected to electric driving mechanism,
Preferably, correspondingly respectively with the electric driving mechanism that two horizontal retractable disconnecting links are connected be fixed on two supports of both sides;
Preferably, the equal correspondence in upper end of lightning arrester is provided with a terminal block, and each terminal block is electrically connected with the horizontal retractable disconnecting link on this terminal block place lightning arrester or disconnecting link contact fishplate bar respectively;
Preferably, two horizontal retractable disconnecting links 3 are all detachably fixed on lightning arrester, make it can change the horizontal retractable disconnecting link of different model, so that horizontal retractable disconnecting link and disconnecting link contact fishplate bar can perfect short circuits;
Compared with prior art, to the utility model major advantage transform former line end lightning arrester, is combined on lightning arrester, decreases floor space, saved ice-melt short circuit disconnecting link construction period and difficulty, reduced costs.
