Power supply cost control system and control method

Abstract

The invention discloses a power supply cost control system and a power supply cost control method. The power supply cost control system is composed of a power distribution device in the voltage classof 10kV or above, a control device of the power distribution device, a power distribution device with in voltage class of 1500V or below, a control device of the power distribution device and a manually-operated controller. The power distribution device in the voltage class of 10kV and the control device are composed of a power transmission line in the voltage class of 10 kV or above, a high-voltage sensor, a high-voltage fuse, a power transformer, an electric energy meter, a special transformer acquisition terminal and an opening remote control module. The power distribution device in hte voltage class of 1500V and below and the control device are composed of a cost control switch, a low-voltage power distribution line and a wireless receiving module. The manually-operated controller is ahand-held closing remote controller, and the surface of the controller is provided with at least one button. The control system can automatically cut off power when a power consumer is defaulting, cannot recover power supply before the consumer paying the electric charge, and can recover power supply only after the power consumer pays the electric charge.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution, and more specifically relates to a high-supply and low-control wireless tariff control switch device and a wireless tariff control method. Background technique [0002] At present, in order to speed up the intelligent construction of power consumption information collection for power customers, realize the improvement of system functions such as real-time monitoring of prepaid electricity charges on the customer side, remote management, power analysis, demand management, etc., and technically realize the "monthly settlement" of electricity bill risks The goal of the work is to control the interference of internal and external human factors from the means, to change the traditional payment mode of customers from the concept, to standardize the order of power supply and consumption from the management, to control the hidden dangers of power customer equipment from the saf...

Problems solved by technology

However, there are still many inconveniences in the application of existing products, which cannot fully cover the needs of the State Grid

For example: the early low-voltage fee control switch only has the function of automatic opening. When the user owes the fee, the fee control switch automatically opens, and the user cannot automatically close the switch after charging, which causes inconvenience to the power user; although the latest fee control switch has the automatic closing function. , but the switch capacity can only meet the electricity demand of residential users, and it is difficult to choose matching low-voltage fee-controlled products for large-capacity dedicated transformer users. The cost is high, the operation risk is high, the approval of high-voltage line operation is strict, and professional operation is required, and the cost control cannot be implemented in time
