The relay protection test power cabinet is my company according to the Department of energy "power plant, substation and relay protection testing instrument configuration quota", "test of relay protection regulations" and "issued by the Ministry of power industry against accidents of power system protection and security automatic equipment measures" of the relevant provisions of the design and manufacture of products. It provides reliable, stable and convenient AC and DC test power for field relay protection test, which provides reliable guarantee for improving the quality of relay protection experiment, ensuring life and equipment safety.

This equipment is suitable for power plants, substations and large and medium-sized industrial enterprises, and can be used as the standard relay protection test power cabinet.

Product characteristics

The power cabinet of relay protection test adopts full closed cabinet structure, front and rear door locks, and the panel is made of plate.

The main components are isolation transformer, three-phase autotransformer, reactor, rectifier, capacitor, automatic air switch, leakage protection switch, ammeter, voltmeter and other components.

The screen has an analog circuit, which makes the operator easy to identify and avoid misoperation.

The instrument, the indicator lamp, the control switch are mounted on the front panel, and the input and output wires can be connected by the terminal and terminal.
