A thyristor pressure indicating device

Abstract

The invention discloses a thyristor pressure indication device; a turning rod pushes a scale rod to slide in an axial direction, and the turning rod motion direction is converted into scale motions; a bearing device is used for limiting a hinge sliding direction, and indicating a pressure value on the scale rod; the bearing device receives external pressure and pushes the turning rod to move, thus further pushing the scale rod to translate; a reset device is arranged between a limit device and the bearing device, so the hinge is pressured to return to the initial position, and the scale is back to zero when the hinge receives no pressure; the thyristor pressure indicating device employs the pure machinery structure, receives external forces through the bearing device, and the limit device can directly make contact with the thyristor, thus providing pressure to the thyristor; when the bearing device receives pressure, the turning rod can form certain displacement, thus allowing the scale rod to translate along the axial direction; the scale rod is provided with corresponding scales, and the displacement amounts are matched with specific pressure values, thus allowing a user to directly see the presently received pressure value without using electric signal transition; the whole process is simple and direct.

Description

Technical field [0001] The present invention relates to the technical field of semiconductor devices, and further relates to a thyristor pressure indicating device. Background technique [0002] The thyristor is a switching element that can work under high voltage and high current conditions, and its working process can be controlled. It is widely used in electronic circuits such as controllable rectification, AC voltage regulation, contactless electronic switches, inverters and frequency conversion. Medium, is a typical small current control high current equipment. [0003] When the thyristor is working, heat will be generated due to the electrical power loss under various transient and steady-state operating conditions. If the heat is not dissipated in time, the heat will accumulate in the device and cause the temperature of the device to rise. When the junction temperature of the device is When its maximum allowable temperature is exceeded, the semiconductor device will fail. ...
