Background technique

A current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side for measurement based on the principle of electromagnetic induction. Before the current transformer is put into use, the waterproof performance of the current transformer is usually tested to reduce the probability of safety accidents due to water infiltration of the current transformer when it is put into use.

For example, the patent with the application number CN202011033489.4 discloses a current transformer detection device, which is inconvenient to move, inconvenient to use, and does not have a good storage device for the existing current transformer detection device. Subsequent use has a great impact on the problem of affecting the use efficiency. The following solution is now proposed, which includes a box body, a number of guide wheels are movably installed at the bottom of the box body, and a first box cover and a second box body are slidably installed on the top of the box body. Two box covers, a first handle is fixedly installed on the top of the first box cover, a second handle is fixedly installed on the top of the second box cover, an installation groove is opened on one side of the first box cover, and a clamping rod is slidably installed in the installation groove. The clamping rod is matched with the second box cover. The present invention is easy to move, can change the position of the detection box according to the use position, is very convenient to use, and can store and place the detection box well for future use.

When the existing detection equipment is in use, most of the water flow will be sprayed inside the detection bin to simulate the humid environment during rainfall.
