Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done concrete introduction.
Fig. 1 is the structural representation of the utility model one embodiment.
As shown in Figure 1: a kind of die heater overtemperature tripgear; Comprise overtemperature tripgear, TM transformer 6 and overtemperature alarm device; The 380V/AC end S of the incoming end of said overtemperature tripgear and fuse 5 and TM transformer 6 is in series, and said overtemperature alarm device is connected with 220V/AC end, fuse 5 and the single control switch 7 of TM transformer 6.
Said overtemperature tripgear comprises QS circuit breaker 1, inlays interior QF dropout of QS circuit breaker (1) and heating tube contactor 2, the pumping contactor 3 that thermal relay FR is installed and the APR-3 phase lost protector 4 on the QS circuit breaker (1) of connecting successively.
Said overtemperature alarm device comprises overtemperature alarm circuit and time delay circuit; Said overtemperature alarm circuit and time delay circuit parallel connection; Wherein, Said overtemperature alarm circuit comprises the time relay 11, thermal light 12, buzzer 14 and temperature controller 13, connects with the normally opened contact e and the d of temperature controller 13 in the said time relay 11, said thermal light 12 and said buzzer 14 parallel connection backs; Said time delay circuit comprises tripping coil 15, and said tripping coil 15 is connected with the normally opened contact f and the g of the time relay 16.
Said overtemperature alarm device also comprise APR-3 phase lost protector 8 with the indicator light 10 mutually of owing of APR-3 phase lost protector 8 series connection; The normally opened contact b of said APR-3 phase lost protector 8 and c are parallelly connected with said overtemperature alarm circuit and time delay circuit, and the normally-closed contact a of APR-3 phase lost protector 8 connects with said overtemperature alarm circuit and time delay circuit.
