A terminal electricity purchase control circuit and method for preventing electricity customers from arrears

Abstract

The invention discloses a terminal electricity purchase control circuit and method for preventing electricity customers from arrears, comprising: a power supply, a metering cabinet and a tripping relay are sequentially connected in series; the remote control device is connected to a terminal acquisition device; The normally open contact K1 of the terminal trip circuit is connected in parallel in the trip control circuit inside the cabinet, and the normally open contact K1 of the terminal trip circuit communicates with the remote control device; a thermistor is connected in series at the output end of the trip relay; The beneficial effect of the present invention is that by adding a terminal tripping circuit in the metering cabinet, the function of remote control of the terminal tripping by staff is realized. When the electricity customer owes the fee, the staff can realize the tripping of the switch of the metering cabinet through the control terminal, which greatly reduces the risk of electricity fee recovery for the power supply company.

Description

technical field [0001] The invention relates to the field of power purchase control for power system marketing business, in particular to a terminal power purchase control circuit and method for preventing electricity customers from arrears. Background technique [0002] The normal recovery of electricity charges is the profit guarantee for power supply companies. When electricity customers default in payment of electricity bills and do not pay electricity bills normally, since the user terminal has no switch trip control circuit, the staff cannot realize the on-site trip of the metering cabinet switch through the remote control terminal, which increases the workload of the staff of the power supply company and is not conducive to Electricity charges are recovered normally. However, one disadvantage of remote tripping is that the remote tripping circuit malfunctions or does not trip when the tripping condition is reached, which will not only cause a certain loss of electric...

AI Technical Summary

Problems solved by technology

When electricity customers default in payment of electricity bills and do not pay electricity bills normally, since the user terminal has no switch trip control circuit, the staff cannot realize the on-site trip of the metering cabinet switch through the remote control terminal, which increases the workload of the staff of the power supply company and is not conducive to Normal recovery of electricity charges

However, one disadvantage of remote tripping is that the remote tripping circuit malfunctions or does not trip when the tripping condition is reached, which will not only cause a certain loss of electricity consumption to the power consumption company, but also increase the workload of the staff of the power supply company
