Abstract
The horizontal lock that the utility model provides moves outdoor AC high-voltage isolating switch, horizontal conductive contact arm is fixedly installed in middle lock and moves insulator top, its two ends are moved tactile portion and both sides and are determined that the stationary contact portion lock of insulator is dynamic to be coordinated, stationary contact portion is horizontal stationary contact post on link plate, described dynamic tactile portion is two parallel row folding fingertips, and between two row folding fingertips, conductive clip touches on stationary contact post.The technical program eliminates flexible member, and designs simplification, conductive contact function admirable, also have the technological merit that time-on in percent is high.
Description
Technical field
The utility model relates to and horizontally rotate double-fracture outdoor AC high-voltage isolating switch, particularly be the conductive contact of described isolating switch.
Background technology
Though below illustrate that the scope of application of Ben Wenben not limit by this illustrative examples with GW7-252 type outdoor high-voltage alternating current isolating switch product for exemplary illustration example.
GW7-252 type outdoor high-voltage alternating current isolating switch is responsible for the non-loaded circuit switching of three-phase alternating current and by high voltage bus, the electrical isolation between circuit breaker and live high voltage circuit of overhauling.Existing level rotates double-fracture outdoor AC high-voltage isolating switch, upper and lower side reed is adopted to increase the pressure with moving contact conductive contact, but the elasticity of reed self can make reed lose bullet gradually because of various environmental factor, material factor, structural factor and time factor etc., conductive contact performance between influencing contactor, also there will be and virtually connects superheating phenomenon; Moreover, existing conductive contact structure also exist because of structural framing stability there is the deviation of certain limit time, and the technical problem of closing a floodgate that causes putting in place.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of and improves conductive contact performance between contact and the horizontal lock closed a floodgate that is easy to put in place moves outdoor AC high-voltage isolating switch.The horizontal lock that the utility model provides moves outdoor AC high-voltage isolating switch technical scheme, its main technical content is: a kind of horizontal lock moves outdoor AC high-voltage isolating switch, horizontal conductive contact arm is fixedly installed in middle lock and moves insulator top, its two ends are moved tactile portion and both sides and are determined that the stationary contact portion lock of insulator is dynamic to be coordinated, described stationary contact portion is horizontal stationary contact post on link plate, stationary contact post is met and is provided with and the dynamic wedge shape guide face touching portion and coordinate to dynamic end of touching portion, described dynamic tactile portion is two parallel row folding fingertips, two row folding fingertip conductions, grip contact on stationary contact post.
Horizontal lock disclosed in the utility model moves outdoor AC high-voltage isolating switch technical scheme, in combined floodgate, the dynamic two row folding fingertips touching portion progress into along the wedge shape guide face of stationary contact post and clamp and are engaged on stationary contact post, folder touches fingertip pressure itself and realizes dynamic, the close contact in stationary contact portion, therefore its electric conductivity is greatly improved, the technical program is without the need to ensureing conductive contact by flexible member, its designs simplification, conductive contact function admirable, in addition, the guiding function of the wedge shape guide face in stationary contact portion relaxes combined floodgate aligning requirements, make two to touch portion and be easy to the cooperation of closing a floodgate that puts in place, improve time-on in percent.

Embodiment
Disclosed in the utility model, horizontal lock moves outdoor AC high-voltage isolating switch, the central authorities of level conduction cantilever 1 are fixedly assembled in middle lock and move on the installation seat 2 on insulator top, the dynamic portion that touches extended to two side ends moves insulator with lock and rotates, close a floodgate with the stationary contact portion that insulator determine in inlet wire side and outgoing line side conduct electricity, separating brake power-off moves and coordinates.
As depicted in figs. 1 and 2, stationary contact portion is for determine horizontally disposed stationary contact post 4 on insulator top terminal block 5, stationary contact post 4 is preferably cylinder or has the cylinder of upper and lower cylinder cambered surface, it is wedge shape that stationary contact post 4 is met to dynamic end of touching portion, and the upper and lower wedge shape guide face 41 of the wedge shape end of stationary contact post 4 plays to the guiding guide effect of stable conductive contact position the dynamic portion that touches.Described wedge shape is preferably taper seat.The dynamic portion that touches is that horizontal conductive contact arm 1 end stretches out the parallel folder fingertip 6 of two fixing rows, and in the present embodiment, the fingertip quantity of every row folding fingertip is two, totally four.During feed motion, when upper and lower two row folding fingertips 6 move to stationary contact post 4 position, the intermediate space place of stationary contact post 4 between two row's parallel clips fingertips 6, the wedge shape guide face 41 of its end guides upper and lower two row folding fingertips 6 to slide cylinder conductive contact closing position to stationary contact post 4, and its own resilient and the stationary contact post 4 of upper and lower two row folding fingertips 6 grip conductive contact.
In the present embodiment structure, for preventing from electrically polluting and the generation of corona phenomenon, stationary contact portion and dynamic touching suspension are all fixed in portion are provided with the combined floodgate place of grading ring 7, two grading ring 7 upper and lower in tactile stationary contact portion with dynamic tactile portion.
