Abstract
The utility model discloses an AC arc extinguishing switching device, wherein a key switch is arranged on a bidirectional controlled silicon trigger circuit, and is connected in series with a resistor inside the trigger circuit used for adjusting a bidirectional controlled silicon conduction angle; moreover, the key switch is also connected in parallel with a high resistance resistor. The switching device eliminates electric arcs generated when a general AC electricity utilization control switch controls the switching on/off of current, thereby preventing consequences such as ablation, burning and explosion caused by the electric arcs; meanwhile, the device smartly arranges the high resistance resistor and the switch inside the bidirectional controlled silicon trigger circuit, and controls the switching on/off of a non-contact heavy current by a safe contact switch energized by microcurrent, thereby ensuring safe electricity utilization and the service life of an electric component; moreover, the device has low manufacturing cost and easy implementation; in addition, the device can be arranged inside a temperature and voltage regulator, an electric water heater and a power socket with a switch, and can also be made into a switch so as to extensively replace alternating current control switches such as contact switch and knife switch which are easy to generate electric arcs.
Description
Affiliated technical field
The utility model relates to appliance field, specifically is a kind of interchange electric control switch device.
Background technology
The switching device majority that present alternating current uses is switch with mechanical contact, the problem of this switch ubiquity discharge spark when switching on and off power termination, especially control the interchange electric switch of big electric current, the electric arc of generation can also burn out consequences such as contact, inducing combustion, blast.
The utility model content
For solving the problem that produces spark when the alternating current switching device switches on and off, the utility model provides a kind of interchange electrical arc switching device that goes out.
The utility model technical scheme of being taked of dealing with problems is: this interchange electrical arc switching device that goes out, comprise key switch and the lead that is connected with key switch, described key switch is arranged on the bidirectional triode thyristor circuits for triggering, with the resistor in series of the adjusting bidirectional triode thyristor angle of flow in the circuits for triggering, and high resistance measurement device in parallel.
The utility model exchanges the safety interchange electric control switch that the electrical arc switching device that goes out is a kind of innovation, it has solved the electric arc that general interchange produces when the Control current break-make with electric control switch, thereby avoided the ablation that causes thus, consequences such as burning, blast, this device is arranged on a high resistance measurement and switch in the The Trigger of Bidirectional Triode Thyristor circuit very cleverly, control the break-make of contactless big electric current with the contact switch that passes to little electric current of safety, guaranteed Electrical Safety and with useful life of electrical component.Simultaneously, this on/off control switch is because the trigger current that passes through is very small, and the contact does not produce arc erosion, and volume dwindles relatively, and it is few to increase components and parts, and cost of manufacture is low, implements easily.The utility model device can be contained in the supply socket of temperature-adjustment pressure-adjustment device, electric heater, belt switch, also can be made into switch, extensively substitutes the alternating current control switch that contact, knife switch etc. are produced electric arc easily.
Description of drawings
Describe the utility model in detail below in conjunction with accompanying drawing.
The circuit diagram that Fig. 1 uses for the utility model.
Embodiment
In conjunction with Fig. 1, switch commonly used comprises key switch and the connector lug that is connected with switch, in electrical arc switching device is gone out in interchange of the present utility model, key switch [1] is arranged on the bidirectional triode thyristor circuits for triggering, the resistor [5] of adjusting bidirectional triode thyristor [2] angle of flow in this key switch and the circuits for triggering is connected, and in parallel with a high resistance measurement device [4], this high resistance measurement is at least more than 100 kilohms.During making, be about to draw binding post in the circuit insertion switch box in the frame of broken lines, promptly make and exchange the arc switch that goes out.Also this circuit can be inserted in the supply socket of temperature-adjustment pressure-adjustment device, electric heater, belt switch.The utility model is arranged on on/off control switch [1] in the circuits for triggering, at switch [1] high resistance measurement device in parallel [4], because the parallel connection of high resistance measurement device [4], when switch [1] when being switched on or switched off, original small trigger current also no longer is a kind of sudden change, the possibility that electric arc produces when then more having eliminated switch [1] break-make, the big electric current of sudden change that neither a kind of thump when influencing principal current thereupon and leading to bidirectional triode thyristor [2] and electrical appliance [3] has prolonged the useful life of all electronic components on the main current channel.
Claims (1)
1. interchange electrical arc switching device that goes out, comprise key switch and the lead that is connected with key switch, it is characterized in that: described key switch is arranged on the bidirectional triode thyristor circuits for triggering, with the resistor in series of the adjusting bidirectional triode thyristor angle of flow in the circuits for triggering, and high resistance measurement device in parallel.
