Remote control device used for remote terminal unit

Abstract

The invention provides a remote control device used for a remote terminal unit, and belongs to the field of remote control. The remote control device comprises a circuit board. A 220V AC power supply, an isolation power supply, a step-down power supply and a microcontroller are arranged on the circuit board in turn. The controlled end of the microcontroller is connected with a control contact. The setting end of the microcontroller is connected with a delay part. The output end of the microcontroller is connected with a relay component. The relay component is also connected with the output end of the isolation power supply. The relay component comprises a relay K which is connected on the microcontroller and also connected on a DC 110V loop. The remote terminal unit is also connected on the DC 110V loop. With application of the remote control device used for the remote terminal unit, operation personnel are enabled to perform remote restart operation on the remote terminal unit at other places without going to the site to perform information checking on the remote terminal unit so that the fault of the remote terminal unit can be effectively solved, the elimination time of the common fault of the remote terminal unit can be shortened and thus the operation and maintenance pressure of the operation personnel can be reduced.

Description

technical field [0001] The invention belongs to the field of remote control, in particular to a remote control device for a remote machine. Background technique [0002] With the gradual expansion of the scale of the power grid, about 2-3 new substations are connected to the control master station every year, and the number of monitoring stations that need to be monitored by the master station is also increasing year by year, and the equipment of the old substations is also aging year by year, and the secondary defects of the substations occur. rate increase. [0003] Among the secondary defects of substations, the defect caused by the remote machine problem accounts for the highest proportion, and 90.5% of the telecontrol defects can be eliminated by restarting the remote machine. Usually the remote motor crashes, and the operator has to go to the site to check the information of the remote motor and solve the fault of the motor, which also brings a lot of pressure on the ...
