Description
Technical field
The present invention relates to a kind of non-electricity protector, refer in particular to a kind of big current three-phase manual anti-leakage protector for heating appliances.
Background technology
At present, the overtemperature power-off protector of electric heater unit, some employing thermally-expansible liquid temperature-sensitive working methods, as: Chinese patent once disclosed one " hand reset over-temperature power-off protector " (China, notification number CN2457728Y, day for announcing 2001.12.27), it comprises the housing of innovative design, thermally-expansible liquid temperature-sensitive part, reset operation part, lever drive part and contactor part, this hand reset over-temperature power-off protector can realize reliable overheat protection function with the version simplified, there is structure simple, low cost of manufacture, dependable performance, high temperature can be adapted to, the advantage of the working environment that high humidity etc. are complicated, be widely used in the overtemperature prote of various large power, electrically heater.But it does not have the function of anti-leak.
Summary of the invention
The object of the present invention is to provide a kind of big current three-phase manual anti-leakage protector, it is for heating appliances, not only has protected by temperature limitation function, and has anti-leak function.
For achieving the above object, the solution that the present invention takes is: a kind of big current three-phase manual anti-leakage protector, it comprises upper cover, base, base plate, the temperature module, temperature-sensitive bag, bellows, reset button, base is arranged push type Self-resetting threephase switch, push type Self-resetting threephase switch comprises the push rod protruding from base plate, when push rod is pressed, circuit disconnects, automatically reset when unclamping and turning circuit, base plate arranges driver plate, driver plate rear end linking springs sheet, the spring leaf other end withstands on base plate, base plate also arranges anti-leak driver plate, two anti-leak stage clips are set below anti-leak driver plate, described anti-leak driver plate is withstood in one end of described two anti-leak stage clips, described two anti-leak stage clip other ends withstand on base plate, anti-leak driver plate is on driver plate, anti-leak driver plate is connected by finely tuning screw rod with driver plate front end, distance between them regulates by finely tuning screw rod, bellows contacts with anti-leak driver plate, back-moving spring plate is arranged on below upper cover, reset button contacts with back-moving spring plate, back-moving spring plate contacts with driver plate.
The work of this big current three-phase manual anti-leakage protector is reasonable to be summarized as follows: when temperature-sensitive bag temperature-sensitive is to design temperature, in temperature-sensitive bag and the temperature module, expansion of liquids promotes bellows, bellows displacement promotes anti-leak driver plate, anti-leak driver plate withstands driver plate below, driver plate is due to the effect of spring leaf, press down push rod instantaneously, circuit disconnects, and realizes 380V-450V power supply and all cuts off; Circuit disconnects, time-outs of heating, the cooling of temperature-sensitive bag, liquid contraction in temperature-sensitive bag and the temperature module, bellows resets, and then manually by reset button, presses down back-moving spring plate, back-moving spring plate presses down and drives driver plate to make it reset, and push rod goes up spring-go position circuit closed condition simultaneously, continues to heat; As when normally working, temperature-sensitive bag temperature-sensitive is lower than design temperature, and protected by temperature limitation part is failure to actuate, and shields when exceeding design temperature, and circuit disconnects; In the process of heating; improper use as a part of in the temperature module or other is when making it fracture and leakage phenomenon occurs, bellows loses thrust instantaneously, does not have pressure on anti-leak driver plate; article two, anti-leak stage clip resilience jack-up anti-leak driver plate; anti-leak driver plate drives fine setting screw rod, and fine setting screw rod pulls driver plate, and driver plate moves downward and presses down push rod; circuit disconnects; temperature no longer rises, and protection use equipment, from damage, now should check that reason changes protector.
