Plug-replaceable type safety electrical converter

Abstract

The present invention relates to a conversion adapter, and more particularly relates to a plug-replaceable type safety electrical converter, which comprises a wiring board. The safety electrical converter is characterized in that the wiring board is connected with a converter control box through a wire. A live wire, a neutral wire and a ground wire are respectively led out of the converter control box. The end tips of the live wire and the neutral wire are respectively provided with connecting sockets and the connecting sockets are in insertion connection with a conversion joint. The end tip of the ground wire is connected with a joint card. The converter control box is respectively provided with a fuse disconnection indicating lamp L1, a power-on indicating lamp L3 and a neutral wire and live wire reserve connection indicating lamp L2. According to the invention, different electrical plugs can be adopted for different cases, so that the operation is safe, reliable, convenient and fast. Meanwhile, the cost is low. The occurrence of personal and equipment damage accidents is avoided, and the working safety is effectively improved. The plug-replaceable type safety electrical converter has good economic and social benefits.

Description

technical field [0001] The invention relates to a conversion adapter, in particular to a safe power-taking converter with replaceable plugs, which belongs to the field of electronic technology. Background technique [0002] At present, in the field work of testing or maintenance, it is often encountered that the power supply of the test instrument is difficult to obtain. The power supply needs to be obtained through a variety of different interfaces, such as two-hole sockets, three-hole sockets, large three-hole sockets, and air switches. There is often only one power plug in the wheel. At this time, the method of cutting off the plug and stripping the wire core to connect to electricity is often used. This method is not only dangerous but also unreliable. Power disconnection, short circuit and joint burnout under heavy load often occur, which is extremely serious. It is easy to cause personal injury and equipment loss, and also brings great hidden dangers to safe production...
