Abstract

The invention discloses a power phase controller based on a single-chip microcomputer, and relates to the technical field of electric power phase control, the power phase controller comprises a phase controller body and a mounting clamping seat, the outer wall of the phase controller body is clamped with the inner side wall of the mounting clamping seat, and an extrusion pre-tightening device is fixedly mounted on the inner side wall of the mounting clamping seat. And a pressed contact device is arranged on one side of the extrusion pre-tightening device. According to the invention, when the phase controller body is placed in the mounting clamping seat, a sealed compressed air bag is extruded through the extrusion pre-tightening device, so that the air pressure in the sealed compressed air bag is changed, and the air flow in the sealed compressed air bag flows into the sealed cavity through the air guide pipe; therefore, a sealing pushing and pressing block in the sealing cavity moves outwards under the thrust action of the air flow, the sealing pushing and pressing block can make contact with the phase controller body according to the thrust of the air pressure, and the stability between the phase controller and the installation clamping base is improved.

Description

technical field [0001] The invention relates to the technical field of power phase control, in particular to a power phase controller based on a single-chip microcomputer. Background technique [0002] The phase controller is an electronic device that controls the DC output voltage by controlling the phase of the trigger pulse. The phase controller can control the current flowing through the switching device, which is connected according to the pulse signal output from the pulse width modulation circuit. on and off. There are following problems at prior art: [0003] 1. At present, during the operation of the phase controller, there will inevitably be some shaking, which will easily lead to collisions between the phase controller and other structures, and the stability of the phase controller will not be good during long-term operation; [0004] 2. When the phase controller works for a long time, it will generate a certain amount of heat. If the temperature cannot be coole...
