Universal variable-frequency power supply suitable for multiple switch connectors

Abstract

The invention discloses a universal variable-frequency power supply suitable for multiple switch connectors. The universal variable-frequency power supply comprises a lower case, an upper case is fixedly installed at the top of the lower case, an observation window is formed in the front face of the upper case in a penetrating mode, a control host is fixedly installed in the upper case, and a case door is installed on the front face of the lower case in a hinged mode. According to the universal variable-frequency power supply suitable for the multiple switch connectors, the mode of a single power strip port of a transmission variable-frequency power supply is changed, a corresponding switch structure can be replaced according to actual use requirements, and the universal variable-frequency power supply is not limited to a first switch connector, a second switch connector and a third switch connector mentioned in the invention, and the universal variable-frequency power supply can be modified correspondingly according to actual use requirements so as to be suitable for a cylindrical connector, a USB connector, a delta-shaped plug and the like; the universal variable-frequency power supply can be widely applied and quite flexible in use; and the connectors and a middle connecting box are connected through an elastic clamping block in a clamping mode, so that assembly and disassembly are quite convenient and rapid, and the connectors are not prone to falling off after being connected.

Description

Technical field [0001] The present invention relates to a field of variable frequency power supply, in particular a suitable multi-switch joint universal frequency conversion power source. Background technique [0002] The variable frequency power supply is the AC → DC → AC transform, and the output is adjustable within a certain range of the output frequency and the voltage. It is different from the variable frequency speed controller for motor speeding, which is different from normal AC regulator power. The ideal activity is characterized by the frequency stability, the voltage is stable, the internal resistance is equal to zero, the voltage waveform is pure sine wave (no distortion). Variable frequency power is very close to the ideal AC power supply, so advanced developed countries increasingly use the variable frequency power supply as a standard power supply to provide the best power supply environment for objective assessment appliances. There are two main types of variabl...

Problems solved by technology

[0003] At present, the frequency conversion power supply on the market is often equipped with a three-wire socket for power supply when it is in use. However, there are many kinds of existing connectors. The use of three-wire connectors for plugging is not conducive to the connection and use of different types of switch connectors. It is not flexible enough and has relatively large limitations. Therefore, a general-purpose variable frequency power supply suitable for multi-switch connectors is proposed.
