The invention discloses a remote control system for on/off of a CT device, and referring to the attached drawing 2, a contactor is arranged between the CT device and a power supply assembly, the contactor is closed, and a channel is formed between the CT device and the power supply assembly, so that the CT device can be electrified; and when the contactor is disconnected and the CT equipment and the power supply assembly are disconnected, the CT equipment is powered off.

It will be appreciated that the present invention incorporates further on/off control of the contactor in addition to the circuit breaker. For the contactor, the invention carries out remote design to realize remote control of the contactor, thereby realizing remote control of CT equipment.

In particular, the system comprises a remote control loop, which in practice may be realized by a length of cable of relatively long dimensions. The contactor is arranged in the remote control loop. The remote control loop further comprises a remote switch, when the remote switch is closed, the contactor is powered on, and when the remote switch is disconnected, the contactor is powered off. Through the closing of the remote switch, the contactor is controlled to be powered on and powered off, so that the CT equipment is controlled to be electrically connected with the power supply assembly, and the CT equipment is controlled to be powered on and powered off.

Further, in a preferred embodiment of the present invention, the contactor is a normally closed contactor, and the remote switch is a normally open switch, that is, normally, the remote switch is open, and the contactor is not powered.

And after the remote switch is closed, the normally closed contactor is powered on and off at the moment, so that the CT equipment and the power supply assembly are disconnected, and the CT equipment is shut down.

Furthermore, in order to ensure the power utilization safety of the CT equipment, the system also comprises a central control module, wherein the central control module is connected with the CT equipment to monitor the power utilization state of the CT equipment in real time. And the central control module is connected with the remote switch, and when detecting that the power consumption of the CT equipment is abnormal, the central control module automatically controls the remote switch to power off the CT equipment. Specifically, the remote switch is automatically controlled to be closed, so that the CT equipment is powered off.

Preferably, referring to fig. 3, L is the outgoing live wire of the power supply end of the CT device, N is the outgoing neutral wire of the power supply end of the CT device, S1 is the remote switch, L1 is the indicator light, and K1 is (the control coil of) the contactor. Specifically, the remote control loop further comprises an indicator light L1, an indicator light L1 is connected with the contactor K1 in parallel, and a remote switch S1 is connected with the indicator light L1 and the contactor K1 in series. When the remote switch S1 is closed and the contactor K1 is powered off, the CT equipment is powered off and shut down, and the indicator light L1 is powered on; when the remote switch S1 is opened and the contactor K1 is powered off and closed, the CT equipment is powered on and started, and the indicator lamp L1 is powered off and extinguished.

Further, the remote switch S1 includes a first contact switch SB1 and a second contact switch SB2, the first contact switch SB1 is connected in series with the contactor K1 for controlling the on/off of the loop of the contactor K1; the second contact switch SB2 is connected in series with the indicator lamp L1 and is used for controlling the on/off of the loop of the indicator lamp L1. The on-off states of the first contact switch SB1 and the second contact switch SB2 are consistent, so that the power receiving states of the contactor K1 and the indicator light L1 are consistent.

In practical applications, the remote switch S1 is embodied as a button, and the initial state of the button is the off state of the remote switch S1.

When the key is pressed down, the remote switch S1 is closed, the normally-open first contact switch SB2 and the second contact switch SB1 are closed at the same time to form a loop, and the key is self-locked; at the moment, the indicator light is turned on and self-locked to indicate that the remote power cut-off is started, the coil of the contactor at the power supply position of the CT equipment is powered on and closed, the normally closed state is changed into the disconnected state, and the original power-on state of the CT equipment is changed into the power-off state.

And pressing the key again, wherein the remote switch S1 is restored to the original off state at the moment, the indicator lamp on the key is turned off, the normally-open first contact switch SB2 and the normally-open second contact switch SB1 are closed simultaneously to form an open circuit, at the moment, the contactor coil at the power supply position of the CT equipment loses power and returns to the normally-closed state again by the open circuit, and the CT equipment is restored to the original power-on state, namely, the restart of the CT equipment is completed.

The invention also discloses a remote control method for the startup and shutdown of the CT equipment, which is based on the remote control system and comprises the following steps:

the closing of the remote switch is controlled, so that the power-on and the power-off of the contactor are controlled, the electric connection between the CT equipment and the power supply assembly is controlled, and the on-off of the CT equipment is controlled;

the central control module is connected with the remote switch and the CT equipment, the power utilization state of the CT equipment is monitored in real time, and when the central control module detects that the power utilization of the CT equipment is abnormal, the remote switch is automatically controlled, so that the CT equipment is powered off.

Preferably, in order to reduce the workload of the central control module, the central control module monitors the power utilization state of the CT device at intervals of a first preset time period, instead of continuously monitoring without interruption. The first preset time period is preferably 5min, or 10min, or longer, and is not limited herein.

Preferably, the central control module automatically controls the remote switch to turn off the CT device after the CT device is powered off after detecting that the CT device is powered on abnormally, and also controls the remote switch to turn off the CT device after a second preset time period, so that the CT device is powered on and turned on. Namely, the equipment restart is completed when the electricity utilization of the CT equipment is abnormal.

Preferably, the central control module automatically controls the remote switch to enable the CT device to be powered off after detecting that the CT device is powered off abnormally, and then the state of the CT device needs to be detected, so as to prevent the situation of shutdown failure caused by the fault of the remote control loop. After the remote switch is controlled to be switched off, the central control module continues to detect and acquire the on-off state of the CT equipment, and if the CT equipment is still in the on state, the signal lamp is controlled to flicker to warn an operator, the remote power-off fails, and the next operation is not required.

It should be noted that the embodiments of the present invention have been described in terms of preferred embodiments, and not by way of limitation, and that those skilled in the art can make modifications and variations of the embodiments described above without departing from the spirit of the invention.
