Description
Technical field
The present invention relates to the appliance switch in the electric elements, relate in particular to the appliance switch that the fire retardant insulating dividing plate is the disjunction medium.
Background technology
At present, international and domestic device for switching is divided into by current forms: alternating-current switch and dc switch.Be divided into by electric pressure: high-voltage switch gear, Medium voltage switch or circuit breaker and low tension switch (containing transfer switching equipment ATS).Be divided into by the disjunction medium: vacuum switch: contact is sealed in the arc control device of high vacuum, and vacuum high insulating property is come arc extinguishing; Insulating oil switch: utilize transformer oil as arc-extinguishing medium; Sulphur hexafloride circuit breaker: adopt the inert gas sulphur hexafluoride to come arc extinguishing, and the very high insulation property of utilizing it to have strengthen the insulation between contact; Solid gas evolving switch: utilize solid aerogenesis material under the high arc temperature effect, to decompose the gas that comes out and come arc extinguishing; Magnetic blow-out switch: during disjunction, the electromagnetic force that the big electric current that utilization itself is flow through produces is elongated electric arc rapidly and is inhaled the indoor cooling of people's magnetic blowout and extinguish.More than be mainly used in height, Medium voltage switch or circuit breaker; Air switch: utilize air to make the disjunction medium and come arc extinguishing.
The basic structure of above-mentioned switch: every utmost point all has a cover contact system; That every utmost point all has is a pair of (or many to), and dynamic and static contact is used to realize separating brake, the closing function of switch; When switch disjunction fault current, can produce strong arc phenomenon between the dynamic and static contact, this is unfavorable for the branch deenergizing; Dynamic and static contact injury for switch self is also very big, the continuous situation of branch can occur when serious.So the breaking capacity of device for switching is a very important index of judging that device for switching is good and bad.And when switch disjunction fault current, the total time of electric arc generating process between the dynamic and static contact, promptly the arcing time has directly determined the breaking capacity of device for switching.
Above-mentioned vacuum switch, insulating oil switch, sulphur hexafloride circuit breaker can very well solve the problem that shortens the arcing time, but As time goes on its vacuum degree or sealing can reduce, and can not keep for a long time, thereby reduce breaking capacity and cost cost height.And the magnetic blow-out switch structure is comparatively complicated, and effect is not so good, belongs to the product of progressively eliminating; With the gas arc extinguishing that it produced, effect is also not so good, generally cooperates usefulness with other scheme separately for the solid gas evolving switch.
The design has solved the drawback of above-mentioned all kinds of switches well.In the design of device for switching disjunction version in the international coverage, be an important breakthrough at home.An important channel of improving the device for switching breaking capacity is provided.
Summary of the invention
The objective of the invention is in order to overcome existing circuit breaker in all deficiencies aspect the realization breaking capacity, the invention provides the switch that a kind of novel circuit breaker is used for high pressure, pressure, low-voltage alternating-current or direct current: a kind of is the appliance switch of disjunction medium with the fire retardant insulating dividing plate.This insulating barrier appliance switch can shorten the arcing time, thereby improve the breaking capacity of device for switching by fire retardant insulating dividing plate breaking arc in dynamic and static contact separates the extremely short time that produces electric arc greatly.
The technical scheme that the present invention takes is: a cover is set between with the dynamic and static contact of air as the air switch of disjunction medium can be with the fire retardant insulating dividing plate of moving contact interlock.When switch on of moving contact, the fire retardant insulating dividing plate is opened under the effect of moving contact linkage, makes dynamic/static contact closed; The effect that the set above that elasticity (or interlock) of fire retardant insulating dividing plate is installed when the moving contact separating brake is in time closed down, with breaking arc.
Each utmost point at switch all is provided with a cover fire retardant insulating baffle plate device: four-pole switch is provided with quadruplet fire retardant insulating dividing plate, and triple-pole switch is provided with three covers, and two utmost point switches are provided with two covers, and single-pole switch is provided with a cover.Narrate with a utmost point of switch at present; The structure of a utmost point of switch is formed and is comprised switch baseplate, Up Highway UHW, fixed contact, banking pin, fire retardant insulating dividing plate, moving contact, moving contact rack, moving contact rotating shaft, connecting rod, compositions such as copper lobe line, rotating shaft cantilever, Down Highway, spring are flexible coupling.
Between the moving contact and fixed contact of this switch, each utmost point is provided with a cover fire retardant insulating dividing plate; This cover fire retardant insulating dividing plate is by forming more than one or two, the fire retardant insulating dividing plate can be up and down or about switching; The fire retardant insulating dividing plate can be with deciliter action interlock of moving contact: promptly the fire retardant insulating dividing plate is opened during switch on of moving contact, during the moving contact separating brake fire retardant insulating dividing plate with and closed.
The shape of fire retardant insulating dividing plate can be tabular, or the shroud shape, can be located on the fixed contact, also can be arranged on the moving contact, also can a cover respectively be set dynamic and static contact simultaneously.
Above-mentioned fire retardant insulating dividing plate can be arranged to two intermeshing steps, certain depth of engagement is arranged to increase creepage distance under closure state.
The fire retardant insulating isolating switch of said structure can be used for high pressure, middle pressure, low tension switch; Also can be used on alternating-current switch or dc switch.
On the base plate of switch, be provided with a cover banking pin at least, be connected with a sleeve spring on the corresponding fire retardant insulating dividing plate of a cover, fixed contact and Up Highway UHW one end are rigidly connected.The moving contact linkage is that a convexity is set on the moving contact rack; Moving contact rack and moving contact are for being fixedly connected; The lower end is connected with switch baseplate through the moving contact rotating shaft, and the back is connected with connecting rod, rotating shaft cantilever, and the moving contact bottom is connected with Down Highway through the copper lobe line that is flexible coupling.When switch prepare to close a floodgate; Moving contact active retrograde clockwise through the rotating shaft cantilever under the drive of moving contact rack and connecting rod rotates and rotates to the fixed contact direction; Linkage on the moving contact rack is opened the fire retardant insulating dividing plate in advance, moving contact is reliably contacted with fixed contact and realizes closing a floodgate; When switch during at separating brake; Moving contact active clockwise direction through the rotating shaft cantilever under the drive of moving contact rack and connecting rod rotates and rotates to the direction of leaving fixed contact; The power of linkage synchronous effect on the fire retardant insulating dividing plate on the moving contact rack is removed gradually; Thereby two fire retardant insulating dividing plates synchronizing close under the effect of spring force is isolated dynamic and static contact, in time breaking arc.Fire retardant insulating is identical with the course of work of the setting of above-mentioned fire retardant insulating dividing plate at a distance from the setting and the course of action of cover, and just its shape is different.
Adopt the beneficial effect of present technique scheme: simple in structure, reliable in action, with low cost, the arcing time when shortening the switch disjunction significantly, thus improve breaking capacity.
