High-voltage load control independent supporting system

Abstract

The invention provides a high-voltage load control independent supporting system. The high-voltage load control independent supporting system is characterized by comprising high-voltage built-in fuses, a single-phase voltage transformer, a built-in safety switch type line bank, an additional breaking coil and a negative control terminal, wherein the input end of the single-phase voltage transformer is connected with a high-voltage bus at the input end of a high-voltage isolation switch of a PT cabinet. The built-in safety switch type line bank is in secondary-wiring connection with the single-phase voltage transformer and is connected with the negative control terminal. The additional breaking coil is connected with the built-in safety switch type line bank and is controlled by the negative control terminal in a remote control mode. The high-voltage load control independent supporting system has the advantages that the input end of the built-in fused type single-phase voltage transformer is connected with the high-voltage bus at the input end of the high-voltage isolation switch of the PT cabinet so that the security of a power grid can be guaranteed; the additional independent breaking coil is controlled by the terminal in a remote-control mode and has no relationship with an original opening coil; only the power supply of the negative control terminal and the additional breaking coil are modified, sealing points are few and sealing processing is easy.

Description

technical field [0001] The invention relates to the technical field of high-voltage substation negative control, in particular to an independent supporting system for high-voltage negative control Background technique [0002] The high-voltage load control terminal is used for power load management of users. The terminal implements local power and electricity control according to the planned power consumption index sent by the mainframe of the power supply company, and sends the user's power parameters and the results of executing the planned power consumption to the mainframe of the power supply company at any time. This not only ensures the implementation of the planned power consumption of the power supply company, but also facilitates self-control and safe production of users. The terminal can accept the remote control command of the host to control the user's load, thereby improving the social and economic benefits of electricity. However, in the actual application pr...

Problems solved by technology

However, in the actual application process, since the negative control terminal borrows the measurement PT, the tripping of the high-voltage cabinet itself, and the related wiring, the property rights of these terminal terminals belong to the user. In order to avoid the control of the negative control terminal technology, some companies privately dismantle the negative control terminal. related wiring or cutting off the power supply of the negative control terminal, so that the negative control terminal loses its due function, which brings great difficulties to the storage of electricity bills, reminders to pay electricity bills, planned electricity consumption, and limit the overcapacity of electricity-consuming enterprises

There is no legal basis for the power supply department to deal with such violations and penalties, and it cannot effectively curb such violations
