The rotary table is provided with the interface board which rotates along with the rotary table, a measuring and controlling device and a cable can be relatively still when the rotary table rotates, the wires are prevented from being twined, the interfaces are prevented from falling off, the flexibility of a test wire is improved, and the wires are prevented from interfering with one another, and the measuring precision is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of anti-radiation interference in meter measurement, and in particular relates to an anti-radiation interface board for testing electronic equipment. Background technique [0002] With the development of society, the electromagnetic compatibility test, which has been neglected in the testing of electronic products, has been paid more and more attention. The radiation immunity and radiation disturbance tests of electronic equipment such as measurement and control devices in power systems are key items to evaluate their performance, and the test conditions for these two tests are very demanding and the test environment is very complicated. [0003] At present, in the testing process of electronic equipment such as measurement and control devices, in order to block radiation interference, the electronic products to be tested are usually placed in a dark room, and the testing equipment is placed in a shielding r...

AI Technical Summary

Problems solved by technology

[0004] In the dark room, the measurement and control device on the turntable is connected to the temporary voltage and current signal wires for testing, and the temporary wires for testing do not rotate when the measurement and control device rotates with the turntable, so that the measurement and control device and the temporary wires move relative to each other, causing the temporary wires for testing to be entangled in the measurement and control On the body of the device, the lines are messy, the wires interfere with each other, the transmission quality is poor, and the wire interface falls off, or the voltage phase is short-circuited, the current is open, and the standard test equipment is burned.

[0005] In addition, since different shielding methods have different degrees of signal attenuation, standard test equipment with different levels, different output powers, and different structures (especially different capacitance and inductance combination structures) should use different shielding methods to transmit voltage and current. Improper use will lead to deviations in measurement accuracy
