Talking about high voltage ceramic capacitor high voltage bridge

High-voltage ceramic capacitors are high-voltage ceramic capacitors used in power systems. Generally, high-voltage ceramic capacitors are used in power metering, energy storage, and voltage division. High-voltage ceramic capacitors have been widely used and not in the LED lamp industry. High-voltage ceramic capacitors are extruded from a high dielectric constant capacitor ceramic into a circular tube, a disk or a disk as a medium, and silver is sintered by infiltration. Plated on ceramic as an electrode.

The high-voltage ceramic capacitor bridge is a device for measuring the ratio of the power-frequency current. It can be considered as a device for measuring the ratio of the power-frequency current from the working principle. When the power frequency high voltage is applied to the high voltage standard capacitor and the device under test, the in-phase and quadrature power frequency current components proportional to their capacitance and dielectric loss factor are generated. The two power frequency current components are generated by the bridge. After the ratio measurement, the difference between the capacitance ratio of the device under test and the high voltage standard capacitor and the dielectric loss factor can be obtained.

High voltage ceramic capacitor bridge classification

1. Xilin type high voltage ceramic capacitor bridge. The current proportional arm of the bridge is composed of a resistor, and a phase shifting capacitor is connected in parallel with the proportional arm flowing through the reference current, and the potential balance indication is used.

2. Current comparator type high voltage ceramic capacitor bridge. The current proportional arm of the bridge is composed of a proportional winding of the current comparator, and a phase shifting circuit is attached to the proportional arm flowing through the reference current, and the magnetic potential balance indication is used. According to the phase shifting method, the bridge can be divided into active and passive. It is a passive one that directly phase shifts with a RC circuit. It is an active electronic component that is matched with RC components. Phase shifting. The magnetic potential synthesis method is used to achieve the desired phase shift.

3. Electronic high voltage ceramic capacitor bridge. A high voltage capacitor bridge that measures amplitude ratio and phase difference using electronic circuits, including analog and digital circuits.

4. Digital high voltage ceramic capacitor bridge. A high-voltage capacitor bridge that measures amplitude ratio and phase difference using a digital signal processing method.

5. High-pressure ceramic dielectric loss meter. A high voltage dielectric loss meter generally refers to a measuring device consisting of a high voltage capacitor bridge, a high voltage test power supply, and a high voltage standard capacitor. The high voltage test power supply is usually not higher than 10KV and the frequency is 40Hz~70Hz.

The high-voltage ceramic capacitor has the characteristics of wear-resistant DC high voltage, and is suitable for high-voltage bypass and coupling circuits. The low-loss high-voltage wafer has low dielectric loss, and is especially suitable for use in circuits such as televisions and scanning. High-voltage ceramic capacitors are only suitable for high-frequency, high-voltage ceramic capacitors depending on the application, typical effects can eliminate high-frequency interference.
