The invention discloses a detection probe of a power module, and belongs to the technical field of smelting rolling equipment detection.The detection probe comprises an insulating tube sleeve and a probe body with a bent part at one end.The end, with the bent part, of the probe body is arranged in the insulating tube sleeve in a penetrating mode, the other end of the probe body penetrates out of the insulating tube sleeve, and a hole for the bent part to penetrate out is formed in the front of the insulating tube sleeve.A supporting column and a spring are arranged between the position, opposite to the hole, of the inner wall of the insulating tube sleeve and the probe body, and a button is arranged at the position, corresponding to the spring, of the insulating tube sleeve.A reflector is arranged at the position, close to the hole, of the front end of the insulating tube sleeve.The detection probe can solve the problems that in detection of the power module, use inconvenience and measurement inaccuracy are likely to occur, and potential safety hazards exist.
Description
technical field [0001] The invention relates to the technical field of detection of smelting and rolling equipment, in particular to a detection probe for a power module on a high-power frequency conversion cabinet. Background technique [0002] A high-power frequency conversion cabinet is connected to the transmission system of the aluminum smelting and rolling equipment. The controller of the frequency converter is composed of various functional modules set on the electronic control board, and the power module is an important part of the controller. When a corresponding fault occurs in the inverter, it is necessary to detect whether the power module is damaged pole by pole. Since there are many terminal heads on the electronic control board of the power module, the terminals to be detected are mixed among the many terminal heads, and the space is narrow; and the detection The multimeter or oscilloscope is used, which is carried out under the condition of electrification. T...
