A current transformer production testing device

Abstract

The invention discloses a current transformer production detection device, comprising a support base, a plurality of locking universal wheels are installed at the bottom of the support base, a current riser and a standard transformer are arranged on the top of the support base, and the support base The two ends are installed with moving devices for adjusting the position of the standard transformer. The present invention drives the adjusting member in the moving device to drive the moving screw to rotate, and realizes the position movement of the standard transformer through the transmission member, so that the standard transformer can be adjusted to The top of the riser reduces floor space and facilitates wiring connections.

Description

technical field [0001] The invention relates to the technical field of transformer detection, in particular to a current transformer production detection device. Background technique [0002] Transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. Current transformers can convert large currents into small currents for measurement or protection systems. Its function is mainly to convert the large current into a standard small current (5A or 1A, both refer to the rated value) in proportion to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. [0003] The current transformer needs to be tested accordingly when it leaves the factory to ensure that the transformer is qualified. In the prior art, the difference measurement method is generally used for the detection of the current transformer. The specific test process is to use the current b...

Problems solved by technology

This verification method is simple and intuitive, and is easy to trace the source. However, the volume of the current riser and the standard transformer required for the verification method are relatively large. If the distribution of the two is relatively wide during the test, it will take up a large space and is inconvenient to carry. , if the two are installed close to each other, there will be unreasonable distribution of positions, which will lead to difficulties in wiring. Therefore, there are great difficulties in the verification of current transformers. Therefore, we propose a production detection device for current transformers
