Abstract
The invention relates to a double-throw isolating switch. The double-throw isolating switch comprises a frame, a contact system, an operating mechanism and the like, is simple, practical and low in cost, can be applied to the serviceable range of isolating switches, overcomes defects of the conventional products, and is provided with a temperature control device, so that the double-throw isolating switch can avoid and reduce various accidents caused by faults such as overload, overcurrent, bad contact, burning-out and the like of the double-throw isolating switch and a controlled circuit.
Description
One, technical field
The present invention relates to a kind of switch, relate in particular to a kind of double-throw disconnecting switch.
Two, background technology
Isolating switch is a kind of electrical equipment of using always, and its safe handling is particularly important, and isolating switch in use has defectives such as overload, overcurrent, loose contact, scorification at present, is prone to cause various accidents.
Three, summary of the invention
For the deficiency and the defective that overcome prior art, the present invention provides a kind of double-throw disconnecting switch, and the present invention can prevent effectively because a variety of causes transships, overcurrent, loose contact, scorification and the accident that takes place.
The objective of the invention is to realize like this:
Double-throw disconnecting switch of the present invention is made up of framework, contact system, operating mechanism etc., it is characterized in that being equipped with on the contact splicing ear attemperating unit, and warning device is housed on the framework.It is characterized in that attemperating unit can be thermostat, temperature switch, thermal protector, thermistor.The temperature-control range that it is characterized in that attemperating unit can be set early warning temperature and break-off signal according to protection range.It is characterized in that attemperating unit can be one two or N.
Advantage of the present invention is following:
Double-throw disconnecting switch of the present invention, simple, practical, cost is low, it goes for the scope of application of isolating switch.It has overcome the deficiency of existing product, has increased attemperating unit, and it can avoid and reduce the various accidents that cause because of faults such as the overload of switch self and charged line generation, overcurrent, loose contact, scorifications.
Four, description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified
Fig. 1 is a double-throw disconnecting switch embodiment sketch map of the present invention
1. double-throw disconnecting switches among the figure, 2. contact, 3. attemperating unit, 4. warning device, 5. framework.
Five, embodiment
Comprise framework, contact system, operating mechanism in the double-throw disconnecting switch (1) in the drawings, on having on the framework (5) contact (2) is arranged, be embedded with attemperating unit (3) on the contact (2), warning device (4) is arranged on the framework (5).
Claims (4)
