Embodiment 1

[0018] Such as figure 1 as shown, figure 2 the connections shown, and image 3 The connection structure of the industrial user first connects the load to the load switch, and when the load is running, the load switch that controls the load is regularly tested, and the load switch is connected to the remote signal detection switch;

[0019] The control center issues a switch output command to the power collection terminal, and the power collection terminal sends a switch control command. If the detection circuit detects that the drive circuit of the load switch is de-energized, the detection circuit will output power according to the de-energization of the drive circuit. The state is on, and the detection input state of the power collection terminal is on, then the detection input state of the power collection terminal determines that the load switch drive circuit is normal, and the signal instruction returns to the determination of the detection input state of the power coll...

Embodiment 2

[0022] According to the same steps as in Embodiment 1, the state of the load and the load switch and the remote signal detection switch are checked irregularly, and the same conclusion can be drawn. From the perspective of economy and rationality, this irregular inspection period is only to ensure the realization of the real-time monitoring of industrial users by the regulatory authorities.

Embodiment 3

[0024] Such as figure 2 As shown, the remote signal detection switch is connected to the detection circuit, and then connected to the terminal switch and the load switch. The structure of the detection circuit is as follows image 3 The structure shown is composed of a power input terminal, a rectifier, a voltage regulator circuit, and a drive output circuit; wherein the power input terminal is connected to the rectifier device, the rectifier device is connected to the voltage regulator circuit, and the voltage regulator circuit is connected to the drive output circuit; in this implementation In the example, the driving current of the driving output circuit is greater than 4mA, the driving output circuit adopts a relay output circuit, the contact is normally open, and the fracture is closed when there is voltage, the relay adopts a micropower signal relay, and the rectifying device is a bridge rectifying device; To achieve the effect of the detection circuit, the inlet of the...

Abstract

The invention discloses a circuit control method, and particularly discloses a method for an electric power competent department to conduct terminal control over electricity utilization units and detect states of the electricity utilization units. The method comprises the steps that when a load is in a running process and a load switch is closed, whether the load switch runs normally is judged through the state of a remote communication detection switch, that is, if the load switch is closed and the remote communication detection switch is in an on state, a detection result shows that the load switch is runs normally, otherwise the load switch runs abnormally; and if the remote communication detection switch is connected with a detection circuit, a better detection effect can be achieved. The method disclosed by the invention has the advantages that the operation is convenient and safe, labor force is greatly saved and the economic effect and the supervision effect are improved. The method can be widely applied to industrial users.

Description

technical field [0001] The invention relates to a circuit control method, in particular to a method for a power authority to perform terminal control and state detection on a power-consuming unit. technical background [0002] In recent years, with the development of the economy and the improvement of people's living standards, the existing power supply can no longer meet the electricity demand of users in peak periods. In order to ensure the people's daily electricity consumption, the electric power department has adopted a variety of power cuts such as shifting peak power consumption and orderly power consumption for industrial power consumption. The final execution unit of these means is a device called "large user load management terminal" by the power company. This device controls the load of the corresponding circuit through 1 to 4 control output switches, so as to meet the requirements of power rationing. [0003] There are some difficulties in the use of this equipm...
