[0014] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0015] Such as figure 1 , figure 2 As shown, an analog device for detecting switchgear supporting control cabinets includes: the core PLC controller unit that controls the normal operation of the entire device, connectors for connecting external cables, and outlet relays 1, 2 for driving output signals 3, 4. Digital display voltmeter, DC220V and DC24V two-way working power supply, power supply protection unit, demand button switch, transfer switch, terminal block, etc. used to detect the working voltage of the power supply and the PT circuit voltage of the tested equipment. External AC380V power is introduced into the terminal block of the analog device, and sent to the DC220V and DC24V working power supply, and the power supply circuit is protected by the parallel power supply protection unit. Monitor the operating voltage of the power supply throu...
