Abstract
A load switch is provided. With the load switch adopted, the problems of complex structure and unreliable potential energy maintaining which are caused by using mechanical maintaining when potential energy is stored can be solved. The load switch includes an operation mechanism; the operation mechanism includes a mounting frame, a fixed iron core and a moving iron core, wherein the movable iron core is in slide moving matching with the mounting frame; a multi-turn coil is arranged inside the mounting frame; the coil is wound on the outer walls of the fixed iron core and the moving iron core; a push rod is sheathed inside the fixed iron core; and one end of the push rod is fixedly connected with the moving iron core, and the other end of the push rod extends out from the mounting frame to be in linkage connection with a transmission mechanism. The operating mechanism is composed of the moving iron core, the fixed iron core and the multi-turn coil, such that the operating mechanism can not only realize original switching-on/switching-off functions, but also can maintain potential energy stored by a switching-off spring, and at the same time, production cost can be decreased.

Background technology
On-load switch is a kind of device for switching between circuit breaker and isolating switch, has simple arc-control device, can cut off rated load electric current and certain overload current, but can not cutting-off of short-circuit electric current.The operation principle of high voltage load switch is similar to circuit breaker, and simple arc-control device generally is housed, and its course of work is: during separating brake, under the effect of operating mechanism, the main shaft rotation moves up piston by slider-crank mechanism, with gas compression on the one hand; The drive system that forms by two cover quadric chains is on the other hand opened first the main switch cutter, then promotes the arc extinguishing plug-in strip arcing contact is opened, and the compressed air in the cylinder is blown out electric arc by spout.During combined floodgate, by main shaft and drive system, main switch cutter and arc extinguishing plug-in strip are rotated simultaneously, arcing contact is closed first; Main shaft is rotated further, and makes main contact closed subsequently.In making process, tripping spring is energy storage simultaneously.Existing stored energy mechanism normally carries out energy storage by tripping spring, then avoid tripping spring to reset by mechanical retaining means, such structure is so that the parts of product are more, and there is complex structure in mechanical retaining means, install inconvenient, use the shortcomings such as unreliable.
Summary of the invention
Adopt machinery to keep for solving in the background technology existing on-load switch when the energy storage potential energy, so that product structure is complicated, potential energy keeps insecure problem, and the utility model provides a kind of on-load switch.
The technical solution of the utility model is: a kind of on-load switch, comprise operating mechanism, tripping mechanism and transmission mechanism, described tripping mechanism links by transmission mechanism and operating mechanism, described operating mechanism comprises installing rack, static iron core and moving iron core, described moving iron core cooperates with the installing rack slippage, be provided with multiturn coil in the described installing rack, described coil winding is at static iron core, on the outer wall of moving iron core, be arranged with push rod in the described static iron core, one end of described push rod and moving iron core Joint, the other end of described push rod stretch out outside the installing rack and transmission mechanism is connected.
As a kind of improvement of the present utility model, described installing rack is provided with position-limit mechanism.
As further improvement of the utility model, described position-limit mechanism comprises postive stop baffle and Limit screw, and described postive stop baffle is connected with installing rack by Limit screw.
As further improvement of the utility model, described moving iron core is threaded with push rod.
As further improvement of the utility model, be arranged with fairlead in the described static iron core, described push rod passes fairlead and transmission mechanism links.
As further improvement of the utility model, described push rod links by U-shaped plate and transmission mechanism.
As further improvement of the utility model, described push rod end is provided with top stem casing and crown bar pin, and described push rod, U-shaped plate, top stem casing are by the crown bar pin Joint.
As further improvement of the utility model, described installing rack is provided with the binding post bent plate.
As further improvement of the utility model, described coil has two circles.
The beneficial effects of the utility model are, consist of operating mechanism by moving iron core, static iron core and multiturn coil, so that operating mechanism not only can be realized original minute, closing function, can be kept by operating mechanism the potential energy of tripping spring storage simultaneously, the potential energy that can effectively keep tripping spring, reduce simultaneously material, reduced production cost, improved greatly the production efficiency of product simultaneously.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Accompanying drawing 2 partly cuts open figure for the utility model embodiment's.
Among the figure, 1, installing rack; 2, static iron core; 21, fairlead; 3, moving iron core; 4, coil; 5, push rod; 51, U-shaped plate; 52, top stem casing; 53, crown bar pin; 6, position-limit mechanism; 61, postive stop baffle; 62, Limit screw; 7, binding post bent plate.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By Fig. 1, in conjunction with shown in Figure 2, a kind of on-load switch, comprise operating mechanism, tripping mechanism and transmission mechanism, described tripping mechanism links by transmission mechanism and operating mechanism, and described operating mechanism comprises installing rack 1, static iron core 2 and moving iron core 3, and described moving iron core 3 cooperates with installing rack 1 slippage, be provided with multiturn coil 4 in the described installing rack 1, specifically, described coil 4 has two circles, can certainly be three, four circles etc.Described coil 4 is wrapped on the outer wall of static iron core 2, moving iron core 3, is arranged with push rod 5 in the described static iron core 2, an end of described push rod 5 and moving iron core 3 Joints, and specifically, described moving iron core 3 is threaded with push rod 5.The other end of described push rod 5 stretches out outside the installing rack 1 and transmission mechanism is connected.The beneficial effects of the utility model are, consist of operating mechanism by moving iron core, static iron core and multiturn coil, so that operating mechanism not only can be realized original minute, closing function, can be kept by operating mechanism the potential energy of tripping spring storage simultaneously, the potential energy that can effectively keep tripping spring, reduce simultaneously material, reduced production cost, improved greatly the production efficiency of product simultaneously.
