Embodiment Construction

[0026] The purpose of the present invention is to provide a hardware external trigger high-voltage electrical test and measurement system based on sequence control, which is used to solve the problem of inaccurate triggering in the prior art when testing and measuring high-voltage electrical appliances.

[0027] To achieve the above object, the technical solution provided by the invention is:

[0028] A hardware external trigger high-voltage electrical test and measurement system based on sequence control, including a measurement host, which is connected with at least one measurement front-end, which is used to connect the detection points in the detection loop; and also includes a trigger circuit, which is connected to the Measuring host;

[0029] At the set time before the start of the test, the trigger circuit sends a trigger command to the measurement host;

[0030] After the measurement host receives the trigger command, it starts to receive the data collected by each me...

Abstract

The invention provides a hardware external trigger high-voltage electrical test measurement system based on sequence control, which includes a measurement host connected with at least one measurement front-end, which is used to connect detection points in the detection loop; also includes a trigger circuit, a trigger circuit Connect the measurement host; at the set time before the test starts, the trigger circuit sends a trigger command to the measurement host; after receiving the trigger command, the measurement host starts to receive the data collected by each measurement front end. Since the measurement host will not receive the signal from the measurement front-end when the trigger circuit does not send a start signal to the measurement host, the probability of the measurement host being triggered can be reduced, thereby reducing the influence of interference signals on the measurement host, and making the measurement trigger and measurement results more precise.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electrical apparatus testing, and in particular relates to a hardware external triggering high-voltage electrical apparatus testing and measuring system based on time sequence control. Background technique [0002] In order to ensure that high-voltage electrical appliances can work normally, they need to be tested and tested. figure 1 It is the schematic diagram of the synthesis test circuit (Sythesis Loop) of the high-voltage electrical apparatus. When the high-voltage electrical test product breaks the short-circuit current in the circuit, a series of changes such as the separation of the moving and static contacts, arcing, arc extinguishing by the arc-extinguishing medium, and the generation of transient recovery voltage occur in a short moment, and the time is about tens of minutes. within milliseconds. The measuring instrument needs to collect the voltage and current of the current sou...
