[0029] Specifically, the input port group can be a conventional three-phase connector. In some embodiments of the present invention, both the input port group and the voltage regulation port group 600 are terminal clamps protruding from the surface of the housing 100. Users can directly connect the wires of the test load to the terminal clamps of the load port group 700 to connect the test load to the load port group 700.

When the timing time reaches the timing threshold, the timing control unit 520 disconnects. When the timing relay 310 loses power, it attracts the first relay switch 320, thereby generating a trigger signal for triggering the switch module 400 to switch on and off.
[0036] In some embodiments of the present invention, as Figure 3 shown, the switch module 400 includes a switch relay 410 and a second relay switch 420.

The voltage modulation unit may include a voltage regulation chip and auxiliary circuits to modulate the voltage input by the power supply and then supply power to the control module 500.

The user can drive the isolating switch 900 to be turned on and off by toggling the driving end, and shut down the timing switch test device in time under special circumstances.
[0043] In some embodiments of the utility model, the voltage regulating component 200 includes a contact voltage regulator, which is an adjustable autotransformer structure. The coil is evenly wound on the annular iron core, and the brush fits tightly with the polished surface of the coil under the action of spring pressure. The rotating shaft drives the brush holder to make the brush slide along the surface of the coil, changing the contact position of the brush and the turns ratio of the primary and secondary coils, so that the output voltage can be smoothly and steplessly regulated within the adjustment range.
[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
