Automatic fault diagnosis device for power electronic circuit

Abstract

The invention discloses an automatic fault diagnosis device for a power electronic circuit. The automatic fault diagnosis device for the power electronic circuit comprises a shell, wherein the left side of the bottom surface of an inner cavity of the shell is fixedly connected with a control device; the right upper corner of the bottom surface of the inner cavity of the shell is fixedly connected with a two-way switch; the right lower corner of the bottom surface of the inner cavity of the shell is fixedly connected with an indicator lamp; a wire clamping column is fixedly arranged on the left side of the shell; the inner side of the wire clamping column is sleeved with a spiral wire; a clamping rod is fixedly arranged on the left side of the spiral wire; a spherical clamping block is formed on the left side of the clamping rod in an integral molding manner; the left side of the clamping block is clamped with a chuck; a supporting device is fixedly arranged on the bottom surface of the shell. By using the control device, the automatic fault diagnosis device for the power electronic circuit achieves the aim of controlling the indicator lamp to remind a person of whether the circuit is damaged; moreover, by using the clamping rod and the spherical clamping block, the chuck is convenient to replace, so the automatic fault diagnosis device for the power electronic circuit can adapt to most of the environments.

Description

technical field [0001] The invention relates to the technical field of circuit diagnosis, in particular to a power electronic circuit fault automatic diagnosis device. Background technique [0002] Nowadays, power supply has become an indispensable energy source in people's life, but the damage of the circuit often troubles people. When the circuit board is damaged, people will use the detection device to detect the location of the damage, and the old-fashioned detection device often uses two The probe pen or two clips are clamped on the circuit to detect the circuit, but when the probe pen detects the circuit, people need to hold the probe pen to detect the circuit, so using the detection device makes people feel very troublesome, so people use the clip instead of the probe Pen, but because the circuits on many circuit boards cannot be clamped, and the clips often accidentally fall off due to people shaking when clamping the circuits, so the clips are not suitable for all c...

[0002] Nowadays, power supply has become an indispensable energy source in people's life, but the damage of the circuit often troubles people. When the circuit board is damaged, people will use the detection device to detect the location of the damage, and the old-fashioned detection device often uses two The probe pen or two clips are clamped on the circuit to detect the circuit, but when the probe pen detects the circuit, people need to hold the probe pen to detect the circuit, so using the detection device makes people feel very troublesome, so people use the clip instead of the probe Pen, but because the circuits on many circuit boards cannot be clamped, and the clips often accidentally fall off due to people shaking when clamping the circuits, so the clips are not suitable for all circuits. At the same time, many detection circuit devices today are not There is no fixed installation device, so when people pull the detection pen, they often pull the detection device together. If you don’t pay attention, the detection device will often be dropped. However, the current detection device is cumbersome to make, and the cost is much higher. It is not conducive to For mass production, we propose an automatic fault diagnosis device for power electronic circuits
