Description
Technical field
The utility model relates to a kind of overheated overcurrent protector simultaneously preventing the too high and electric current of circuit temperature excessive.
Background technology
Overheat protector is installed in circuit, and when circuit is overheated, its internal circuit disconnects, thus disconnects whole piece loop, prevents circuit overheated and breaks down.Overcurrent protector is installed in circuit equally, and when the magnitude of current in circuit exceeds set point, its internal circuit disconnects and cuts off whole piece loop, prevents electric current excessive and occurs contingency.These two kinds of circuit brakes are arranged among circuit respectively, can carry out overtemperature protection and overcurrent protection respectively to circuit, but this needs among circuit, set two installation sites respectively, causes complex circuit, difficult in maintenance; Two need to increase many electric wires, cause the increase of cost; Three also cause the necessary corresponding increase of the volume of equipment, and in circuit brake field, the equipment of excessive bulk is difficult to apply in multiple product, so not only add cost but also affect its scope of application.
Summary of the invention
The utility model aims to provide a kind of overheated overcurrent protector that simultaneously can prevent the overheated and overcurrent of circuit, to simplify circuit, reduces costs and equipment volume, improves its scope of application.
Overheated overcurrent protector described in the utility model; comprise the attemperating unit with temperature opening and closing; with the heating wire of heating after energising; inside is had to have the base of stepped concave station; heating wire is arranged in lower floor's ladder of concave station; attemperating unit is arranged on the upper strata ladder of concave station, and an electrode on attemperating unit and one end of heating wire are electrically connected, and another electrode of attemperating unit is connected external circuit respectively with the other end of heating wire.
Overheated overcurrent protector described in the utility model; attemperating unit and heating wire series connection; be integrated by base combination, an electrode of attemperating unit is connected with circuit respectively with one end of heating wire again, is a loop with the equipment connection of circuit and required protection.During work, electric current flows through attemperating unit and heating wire successively along circuit, when device temperature or operating temperature too high time, namely attemperating unit disconnects, and plays the effect of temperature protection; And when circuital current is excessive, electrothermal wire heating also affects attemperating unit and makes it disconnect, and namely plays the effect of overcurrent protection.This protector mainly utilizes the temperature control principle of attemperating unit, and its structure is simple, effectively, with low cost and be easy to realize; Attemperating unit and heating wire connect as one by base, greatly can be reduced complexity and the maintenance difficulties of circuit, reduce costs simultaneously and reduce equipment volume, expand its scope of application by this kind of simple structure; Chassis interior is provided with stair-stepping concave station, attemperating unit and heating wire are arranged in the upper and lower ladder of concave station respectively, both the stability of its work can have been ensured, both directly contacts can be avoided again, thus cause the change of heating wire setup parameter or heating wire to cause attemperating unit work because transferring heat is excessive under the state of low current, effectively ensure its job stability and accuracy.
