Thin-film capacitor frequency temperature rise detection device

Abstract

The invention relates to the technical field of capacitance detection equipment, and discloses a thin-film capacitance frequency temperature rise detection device which comprises a detection box body,a display screen is fixedly mounted on the front surface of the detection box body, and an indicator lamp is fixedly mounted on the front surface of the detection box body and located below the display screen. An adjusting knob is fixedly installed on the front face of the detection box body and located on the right side of the display screen, a control button is fixedly installed on the front face of the detection box body and located below the adjusting knob, and a base plate is fixedly installed at the top of the detection box body. According to the thin-film capacitor frequency temperature rise detection device, a draught fan and an electromagnetic valve are started to be opened, the draught fan sucks external cold air into a uniform distribution pipe and a separation box through a filter box and a hose, heat dissipation is conducted on the separation box, and the situation that too large detection data deviation is caused due to the fact that subsequent detection is influenced bytoo much heat in the separation box is prevented; and the effect of high-precision detection is achieved, so that the practicability of the detection device is improved.

Description

technical field [0001] The invention relates to the technical field of capacitance detection equipment, in particular to a thin film capacitance frequency temperature rise detection device. Background technique [0002] There are many types of capacitors depending on the medium, such as: electrolytic capacitors, paper capacitors, film capacitors, ceramic capacitors, mica capacitors and air capacitors, etc., but the most frequently used in audio equipment are electrolytic capacitors and film capacitors. Capacitors, electrolytic capacitors are mostly used in places that require a large capacitance, such as the filter capacitor of the main power supply, in addition to filtering, and also used to store electric energy, while film capacitors are widely used in the analog signal exchange Connection, power supply noise bypass (reverse cross-connection), etc., the film capacitor uses metal foil as the electrode, and it is laminated with plastic films such as polyethylene, polypropyl...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a film capacitor frequency temperature rise detection device, which has the advantages of high detection efficiency, and solves the problem that the traditional film capacitor detection device generally uses a single detection, and its detection efficiency is low, and the traditional film capacitor The detection device has no heat insulation and heat dissipation functions, and is easily affected by the external temperature, which causes the problem of excessive deviation of the detection data.
