For achieving the above object, the solution that the utility model adopts is: a kind of bipolar disconnection non-automatic-reset thermal circuit beraker, it comprises base, lid, fixed contact, movable contact spring and moving contact, the temperature module, the temperature module has probe and bellows, probe and bellows are seals, fill in the seal with the liquid that expands with heat and contract with cold, the spring terminal is inserted on a left side, the right openend of inserting the spring terminal is tightened by jump ring, the spring terminal is inserted on a left side, the right spring terminal of inserting has left sheet of being connected of fixed contact with riveting respectively, connecting right sheet is riveted into one, connect left sheet, connect right sheet and base riveted and fixed, two square binding posts of being furnished with the clamp bolt respectively be connected left plate, connecting right panel is riveted on the base, the movable contact spring that two rivetings have a moving contact respectively be connected left sheet, connecting right sheet is fixed on the base, mechanism rack is assemblied in the base, link plate is housed on the mechanism rack, the link plate other end and impeller riveted joint, the impeller lower end is contained on two movable contact springs, the mechanism rack other end is equipped with seesaw, be welded with restoring lever on the seesaw, be equipped with between seesaw and the link plate and lift up sheet, stage clip II is housed on the boss of base, insulation cushion is housed on the base, the centre bore of insulation cushion is equipped with stage clip I, insulation cushion one end is equipped with micrometer adjusting screw, the other end is equipped with the push rod that resets, the temperature module one end is contained in the stage clip I, the other end is contained in the adjustment screw in the lid, lid, insulation cushion, base connects by two M3 * 25 screws.
The probe sensing equipment temperature of the temperature module.Temperature raises in the equipment; expansion of liquids in the temperature module; bellows moves downward; force link plate and impeller to move downward; when temperature reached the temperature of setting, the strength of this continuous transmission made impeller be enough to drive the upwards action of two movable contact springs; moving contact and the two poles of the earth fixed contact disconnect synchronously on two movable contact springs, to reach the purpose of the protection equipment of cutting off the electricity supply.When temperature dropped to uniform temperature, because seesaw and the existence of lifting up sheet, the two poles of the earth contact can't reset, and needed the hand-reset push rod just can make seesaw and lift up sheet and resetted, and drove link plate and resetted, thereby the two poles of the earth contact is resetted, and equipment could energising work.
It can guarantee to disconnect synchronously the two poles of the earth contact, by just resetting manually, to reach the purpose of the protection equipment of cutting off the electricity supply.
