A terminal electricity purchase control circuit and method for preventing arrearage of electricity customers

Abstract

The invention discloses a terminal electricity purchase control circuit and method for preventing arrearage of electricity customers. The terminal electricity purchase control circuit comprises a power supply, a metering cabinet, a tripping relay, a remote control device and a terminal acquisition device, wherein the power supply, the metering cabinet and the tripping relay are in series connection in sequence; and the remote control device is connected with the terminal acquisition device. A tripping control loop in the metering cabinet is connected in parallel with a normally-open contact K1 of a terminal tripping loop; the normally-open contact K1 of the terminal tripping loop is communicated with the remote control device; and the output end of the tripping relay is connected in series with a thermosensitive resistor. The beneficial effects are that, by adding the terminal tripping loop to the metering cabinet, terminal tripping remote control of working personnel is realized; and when an electricity customer is in arrears, the working personnel can controls the terminal to realize switching tripping of the metering cabinet, thereby greatly reducing the risk of electricity charge recovery.

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
