Description
Technical field
The utility model relates to a kind of electric power equipment, relates in particular to a kind of electric power outdoor single pole isolating switch.
Background technology
The electric power outdoor single pole isolating switch that uses is widely used in the overhead transmission line that electric pressure is 10KV at present, and it is made of installing rack, insulator, fixed contact, moving contact.And the most of single-pole isolators that are used for overhead transmission line have a common shortcoming, promptly adopt a pressure regulating spring device to be fixed on the pressure of regulating dynamic/static contact on the moving contact, cause discontinuity equalization, easy deformation, moving contact and fixed contact are easy to generate the gap, contact-making surface is less, become flexible easily at the fixing position of moving contact, heating even produce high temperature and cause the contact part to be burnt easily by powerful electric current the time, contact resistance is increased, shorten the useful life of switch, and brought the difficulty of great line loss, maintenance and replacing to power supply department.
Summary of the invention
The purpose of this utility model is to overcome shortcoming of the prior art, but provide a kind of dynamic/static contact contact-making surface big, can anti-powerful electric current and the electric power outdoor single pole isolating switch that inserts of two ends fixed contact two-wire.Technical scheme
A kind of electric power outdoor single pole isolating switch comprises installing rack, insulator, fixed contact, moving contact, axle screw rod, and fixed contact comprises contact base, contact block, studdle, spring, setscrew nut, and described contact base is the U type, and its bottom is fixed on the insulator; The both sides of each contact base are provided with several spring cavitys to outer lug symmetrically, make whole static contact structure compactness and can play the dustproof effect.Spring cavity is provided with screw hole, passes to make things convenient for studdle, and an end and the contact block of studdle are hinged, and the cover upper spring, and the other end passes screw hole, setscrew nut on the rotation set.Can adjust the intermittence of contact block by turning setscrew nut, contact base and being provided with above the contact block is used for the circular hole hinged with moving contact.
Both sides are provided with respectively 1～4 of spring cavity, studdle, spring, setscrew nut symmetrically on the described contact base.
Described moving contact is fixedly formed by two copper coin therebetween one block plates, when closing a floodgate, moving contact is embedded between two contact blocks of another contact base by the operation ring on the steel plate, contact block can open the length of spring compressed contact block to both sides, moving contact is incorporated into, simultaneously contact block is contacted with moving contact very good, during separating brake that the operation hoop of steel plate is drop-down, promptly moving contact disengages piece, and two contact blocks can automatically reset under the effect of spring.
The utility model compared with prior art has following advantage:
1, the both sides of each contact base of the present utility model are provided with several spring cavity and several compression spring devices to outer lug symmetrically, be difficult for producing the gap between not only dynamic and static contact, contact-making surface is big, stressed even, not yielding, and anti-powerful electric current, the construction of switch compactness, fixed contact can play the dustproof effect.But switch ends also two-wire inserts.
2, moving contact of the present utility model is provided with two copper coins and presss from both sides a block plate, and the intensity height is not yielding, easy to operate.
3, of the present utility model rational in infrastructure, not only kept good electrical conductivity, and it is low to consume energy, safe and reliable, long service life, the scope of application is wide.
