Due to the centralized installation of the control button and signal device on the control box, the analog test control device of the switch cabinet is small in size, and it is not necessary to purchase a large number of large-scale test devices to carry out the analog test of the switch cabinet, which is economical and suitable for a large number of analog switch cabinet experiments. Moreover, it can intuitively control the components on the control box, so that the installation and fixing are more flexible, the volume is small, and the experimental device is miniaturized, which can be applied to the simulation switch cabinet experiment without the bulky test bench.

Good authenticity: According to the physical switch cabinet design, the real simulation of various office discharge faults inside the switch cabinet.
Fault simulation: can simulate switchgear tip, suspension, air gap, particles, along the surface and other discharge types, multiple discharges can be combined.
Controllable discharge: The type of discharge can be arbitrarily selected to control the initial voltage, extinction voltage and discharge intensity of each discharge signal.
Diversified detection: It can provide test platform for pulse current, UHF, ultrasonic, transient ground voltage and other technical detection.
Measurement transmission: Built-in pulse current method correlation coupling, calibration unit, can synchronously detect the level of the experimental device, as the basis for instrument assessment.
Good stability: each discharge module can be reused and the discharge characteristics are stable.
Visualization: Built-in infrared video probe, easy to observe the internal state, capture discharge video.
Convenient operation: the generation and disappearance of various faults can be directly controlled outside the device.
Safe and reliable: the booster equipment is built in, the high pressure is isolated from the outside world, and the operation is safe and reliable.
