Abstract
The utility model relates to a safe and energy-saving capacitance contactor accessory which is externally connected on a contactor to break the charging inrush current after forced discharge, so as to ensure the normal operation of the contactor. The capacitance contactor accessory comprises a casing, a static contact pad, a contact bridge, contact supports, a resistance wire, etc. A moving contact spring leaf with one end connected with the resistance wire and the other end elastically contacting with the static contact pad is additionally arranged between the resistance wire and the static contact pad. When the contactor main contact is not closed to conduct circuit, the contact supports in the accessory are driven to slide, so that the contact bridge conducts the resistance wire on the static contact pad and the inrush current of the capacitor is forcedly discharged; and when the contactor main contact closed to conduct circuit, the contact supports on two sides are driven to continue sliding to push away the moving contact spring leaf, so that the static contact pad is in disconnected state again and the resistance wire is not conducted. The improved structure can instantaneously break the resistance wire current to close the contactor main contact to conduct circuit, so as to effectively prevent the resistance wire in the contactor accessory being burnt out due to long-term conduction after discharge, resulting in more safe and energy-saving performance.
Description
Technical field
The utility model relates to a kind of outer charging inrush current that makes capacitor on the contactor that is connected on and obtains forcing the energy-saving safe capacitor switching contactor annex of releasing.
Background technology
Capacitor switching contactor in use often needs external annex, its objective is by annex and reach the charging inrush current of forcing the vent discharge container, to guarantee the contactor operate as normal, existing capacitor switching contactor accessory structure roughly comprises the housing that plastics are made, be embedded with a pair of static contact panel in the housing, and be connected to resistance wire on the every static contact panel, resistance wire is connected in the contactor again simultaneously, between two static contact panels, be provided with the contact support that resets by torsion spring, be provided with the contact bridge of spring reset in the contact support.Can drive contact and support slippage after the capacitor switching contactor energising, two static contact panels of contact bridge contact make the charging inrush current of capacitor be forced to release by resistance wire, and contactor main contacts closure is sent electricity, gets final product operate as normal.Yet, the capacitor switching contactor annex of existing structure is after the contactor energising, resistance wire all is to be in closure state always, when main noddle on contactor contacts bad, resistance increases, electric current can be switched on by resistance wire, and overlong time burns out resistance wire easily, so often there is the defective that security performance is lower and waste electric energy in this accessory structure.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and a kind of safe and energy-conservation capacitor switching contactor annex that has is provided.
Technical problem of the present utility model is achieved through the following technical solutions:
A kind of energy-saving safe capacitor switching contactor annex, be embedded with several in the housing of this annex to static contact panel, and be connected to resistance wire on the every static contact panel, at the terminal connector that plugs with contactor that connects of resistance wire, between static contact panel, be provided with the contact support that resets by torsion spring, be provided with the contact bridge of spring reset in the contact support, this contact bridge is subjected to contact support slippage and static contact panel or branch or closes, it is characterized in that being connected with between described static contact panel and the resistance wire moving contact shell fragment, one end of this moving contact shell fragment is connected on the resistance wire, and other end Elastic Contact is on static contact panel; Described contact support is provided with the catch of pushing tow moving contact shell fragment.
Described several be a pair of or two or three pairs of to static contact panel.
Compared with prior art, the utility model is provided with the moving contact shell fragment between the resistance wire of capacitor switching contactor annex and static contact panel, when the capacitor switching contactor energising, when main noddle on contactor is not closed, the contact that drives earlier in the annex of both sides is supported slippage, and make resistance wire on the contact bridge conducting static contact panel of contact in supporting, after the charging inrush current that makes capacitor is forced to release by resistance wire, the closed energising of main noddle on contactor, the contact support of both sides annex also can continue the slippage pushing tow and hold this moving contact shell fragment, make that resistance wire is in off-state again on the static contact panel on both sides, structure after the improvement can disconnect annex internal resistance wire electric current in the moment of working, make contactor main contacts closure send electricity, effectively prevent to switch on for a long time after contactor annex internal resistance wire from discharging and burnt out, so have safety and energy-saving advantages more.

Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1～shown in Figure 5, a kind of energy-saving safe capacitor switching contactor annex comprises the housing by the engineering plastics injection mo(u)lding, and housing is formed by pedestal 1 and cover plate 12 mutual snappings, and affixed with screw.Be provided with rectangle slotted eye 13 at the outer surface of cover plate 12 near medium position, this slotted eye one side be provided with can snap onto the contactor both sides only detain 14; In pedestal 1, be embedded with two pairs of static contact panels 7 that are square profile, but left and right two static contact panels respectively constitute the circuit of a pair of conducting simultaneously, on each static contact panel, respectively be connected with a resistance wire 8 by screw 6, this resistance wire end passes housing and connects connector 11, and is plugged in the contactor with connector.Also be provided with simultaneously the contact that lays respectively between the static contact panel 7 and support 2 in pedestal 1, contact support below is provided with the torsion spring of reset response, and this torsion spring one end is embedded in translot 17, and the other end contacts on housing.The contact support is provided with the pushing block 15 with its disjunctor, and this pushing block passes the rectangle slotted eye on the cover plate, and can be in the top of slotted eye 13 under the effect of torsion spring 10 below the contact support 2 always, and this pushing block is promptly driven downward slippage after the capacitor switching contactor energising.Be provided with the contact bridge 5 that resetted by two springs, 3 downward pushing tows in the contact support 2, this contact bridge can contact two static contact panels 7 that are positioned at its both sides after the downward slippage of contact support, and this moment, the charging inrush current of capacitor was promptly forced to release by resistance wire.
Simultaneously between the static contact panel 7 of diagonal position and resistance wire 8, also be provided with moving contact shell fragment 9, one end of this moving contact shell fragment is connected on the resistance wire, other end Elastic Contact is on static contact panel, move down in contact support 2, the a pair of static contact panel 7 of contact bridge 5 conductings, after resistance wire carries out current drain, support under 2 effects at the contact that continues to move down, catch 16 pushing tows that original moving contact shell fragment 9 one ends that contact with static contact panel 7 are promptly stretched out in the contact support 2 are opened, this moment, electric current was interrupted again, the phenomenon that has been burnt out so effectively avoided the long-term energising of contactor annex internal resistance wire.
