Abstract
An electron switch facility safely separates electrical apparatus with anti-lightning strike and saving electricity. The main part of it relates to supporting plate, driver and electromotor. On the top of supporting plate, there are electromotor, driver and definite switch, which is for limiting the action of switch with moving-contact. Electromotor connects with driver, and switch with moving-contact is on the driver and is able to move with driver to the switch with immovable-contact, while the latter is fixed on supporting plate or shell, and the close and open of switch is carried by the opposite movement of switches with moving-contact and immovable-contact. The driver is a gear, a gear mechanism in type of strap, or a chain mechanism. This purpose of this separates electrical source effectively with safe disconnection distance, avoids lightning strike to save energy.
Description
Technical field
The present invention relates to a kind of electronic switching device, especially a kind of can be effectively anti-lightning strike and the safety isolated switch of electrical appliance of saves energy.
Background technology
Along with popularizing of electrical equipment, safety utilization of electric power, lightning protection and saves energy are the important topics that needs to be resolved hurrily at present.For adaptive technique updates and networked growth requirement, appliance manufacturers has been developed remote control switch, has been continued various idle functions such as digital demonstration, WOL, timing switch, these functions provide a large amount of convenience for the user, but have also caused problems simultaneously.As television set operation for convenience, generally can realize standby and startup once more by remote controller, but being in television set under the holding state for a long time can cause considerable electric energy to expend and have the potential safety hazard that is difficult to expect, thunder and lightning when invasion particularly arranged, and high-tension current even can break is in the television set under the ac dump state.In addition, the mains switch of the television set that has is located at transformer secondary output, and this television set only closes switch, does not pull out attaching plug, also can make the long-term unloaded charged and consume electric power of television set transformer.Therefore, have only plug pulled out and to prevent to respond to thunder and circuit pulse effectively and damage television set and stop unnecessary electric energy and expend.Simultaneously, the work of need switching on when the supply load electricity consumption of the relay contact control system of present most control circuits causes a large amount of waste of energy.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art and provide a kind of instructed when disconnecting with dump and to keep the safety isolated switch of electrical appliance of certain break distance.This safety isolated switch of electrical appliance major part is body supporting bracket, transmission mechanism and motor, motor, transmission mechanism are arranged on the body supporting bracket and be used to limit the qualification switch of switch moving contact stroke, motor links to each other with transmission mechanism, the switch moving contact is positioned on the transmission mechanism and can moves to switch fixed contact direction with transmission mechanism, the switch fixed contact is fixed on body supporting bracket or the housing, realizes that by carrying out relative motion the disconnection of switch is with closed between switch moving contact and the switch fixed contact; Transmission mechanism can be gear, banded flat toothed mechanism, also can be link chain mechanism.The present invention has following beneficial effect: effectively carry out isolated from power, keep safe break distance, prevent thunderbolt, saves energy.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and concrete execution mode essentiality content of the present invention is described in further detail.
Shown in the adjoint, this safety isolated switch of electrical appliance major part is body supporting bracket 6, transmission mechanism 5 and motor 4, motor 4, transmission mechanism 5 are arranged on the body supporting bracket 6 and be used to limit the qualification switch 3 of switch moving contact 2 strokes, motor 4 links to each other with transmission mechanism 5, switch moving contact 2 is positioned on the transmission mechanism 5 and can moves to switch fixed contact 1 direction with transmission mechanism 5, switch fixed contact 1 is fixed on the body supporting bracket 6, realizes that by carrying out relative motion the disconnection of switch is with closed between switch moving contact 2 and the switch fixed contact 1.Transmission mechanism 5 is gear 7, banded flat tooth 8 mechanisms.During work, when being under the power-off state, motor 4 is received work order need carry out switch closure, motor 4 actions this moment and the switch moving contact 2 that drives on the transmission mechanism 5 move to switch fixed contact 1 along body supporting bracket 6, contact with switch fixed contact 1 until switch moving contact 2 and realize switch closure; Vice versa, motor 4 is received work order need carry out switch when disconnecting, switch moving contact 2 on motor 4 actions and the drive transmission mechanism 5 towards 1 counter motion of switch fixed contact, realizes that until switch moving contact 2 and switch fixed contact 1 switch disconnects fully along body supporting bracket 6.Under the situation of ac dump, the distance that disconnects between the switch contact is very short as colour TV, and high-tension current can puncture easily, has the hidden danger of being struck by lightning.Have only certain break distance of maintenance could effectively isolate thunder and lightning between the contact of switch.This switch instructed the break distance that has kept 4cm when disconnecting between the switch moving contact and switch fixed contact, stopped the unnecessary electric energy of electrical equipment and expended and effectively eliminate because of the many unsafe factors due to for a long time charged.As the spike absorber element being housed in the civil power side, lightning induction pulse and electrical network surge voltage are effectively absorbed land, greatly improved the safe in utilization of electrical appliance.Simultaneously, finish the work of suffered instruction when motor after, enter not electriferous state immediately, be subjected to the support of motor and transmission mechanism, the contact reliably is switched on or switched off.When this switch is used for the relay contact control system of some control circuit, can realize that the relay contact control system need not energising work when the supply load electricity consumption, thus saves energy.
Claims (2)
