Time-delay closing type fee control system

Abstract

The invention provides a time-delay closing type fee control system, and the system comprises a load management loop which comprises a load management terminal FK1 which is electrically connected with an electricity selling controller, and is used for receiving arrearage information and payment information, and issuing a corresponding instruction; a tripping loop which comprises an automatic tripping loop, wherein the automatic tripping loop is in communication connection with the load management loop; a closing loop which comprises an automatic closing loop, wherein the closing loop is in communication connection with the load management loop; a delay control loop which is respectively in communication connection with the load management loop and the closing loop. The load management terminal receives arrearage information and sends a tripping pulse signal, the load management loop controls the automatic tripping loop to be switched on and triggers the delay control loop at the same time, and the delay control loop is used for controlling the closing loop to be switched on and delayed until the load management terminal receives a payment signal; and the load management terminal receives the payment information, and the automatic closing loop is switched on. According to the invention, fee control automatic buffer closing is realized, the power utilization efficiency is improved, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of electric energy fee control, and in particular relates to a delay closing type fee control system. Background technique [0002] The electricity sales management device is a device specially developed to solve the problems of remote meter reading and remote control of electricity charging in the power sector, which integrates power metering, remote communication, prepayment and anti-theft functions. [0003] It is suitable for large, medium and small box-type high power supply users with AC rated frequency of 50Hz, rated voltage of 10kV, rated current of 1250A, that is, capacity of 315kVA and below. The current level includes each current between 630A and 1250A, and is composed of a power sales controller, a three-phase electric energy meter, a pole-mounted vacuum circuit breaker, a control system, and a cabinet. [0004] At present, in the ZKW32 integrated high-voltage prepayment system operating in the...

AI Technical Summary

Problems solved by technology

[0004] At present, in the ZKW32 integrated high-voltage prepayment system operating in the power grid, there is usually a vacuum breaker switch on the terminal control column to realize the function of opening and closing the fee control. The closing button can be directly closed again, and the automatic closing of the fee control cannot be realized. The customer needs to go to the site to manually close the switch to restore the power supply after each arrears and power outage payment; For the low-voltage switch, a set of electric operating mechanism is installed on the molded case circuit breaker to realize the opening and closing function of the switch. In the actual operation process, after the molded case circuit breaker is opened, it is necessary to press the closing button again to directly close again. and prone to misuse

For the WSDY box-type low-voltage prepayment system, an electric operating mechanism is usually installed on the basis of the molded case circuit breaker, but the mechanical reliability is low, and it is easy to misconnect and misconnect in the electrical aspect, which affects the power supply efficiency
