Intelligent prepayment control system

Abstract

The invention discloses an intelligent prepayment control system, comprising: a high-voltage vacuum circuit breaker switchgear, a high-voltage metering combination transformer and a prepayment metering box, the high-voltage metering combination transformer is a combination of a current transformer and a voltage transformer As a result, the current transformer is installed on the moving end outlet of the high-voltage vacuum circuit breaker switchgear, and the prepaid metering box includes a prepaid metering system, a metering collection terminal and a system management unit. The invention has intelligent control, environmental protection and energy saving, satisfies the functions of remote control, remote measurement and remote signaling, and can be used with DTU and FIU distribution network. By combining high-voltage vacuum circuit breaker switchgear, high-voltage metering combination transformer and prepaid metering box into a system, In the case of power theft or phase loss, the metering can automatically open the circuit breaker according to real-time monitoring, and at the same time send a fault alarm to the power failure control, which has anti-theft, anti-freeze, and high-temperature performance.

Description

technical field [0001] The invention relates to a control system, in particular to an intelligent prepayment control system. Background technique [0002] With the steady development of my country's modernization, the contradiction between supply and demand in the power industry is becoming more and more prominent. In order to gradually eliminate the phenomenon of power theft and arrears, reduce the loss of power equipment itself, improve enterprise efficiency, and safeguard the legal rights of power investors and operators, various All kinds of power equipment manufacturers regard how to reduce the loss of power equipment itself and the research of anti-stealing technology, improve the measurement accuracy of power metering equipment, and cooperate with the power department to promote and carry out prepayment control, as an important work that enterprises often pay attention to. In the existing technology, the rural power grid and urban power grid of the power system still h...

Problems solved by technology

In the existing technology, the rural power grid and urban power grid of the power system still have an outdoor pole-mounted control and protection method with a combination of isolating switch and drop insurance. The protection of this scheme is unreliable, causing frequent power outages for users and increasing the workload of the power supply department; Although part of the power grid transformation has been replaced with a circuit breaker protection control system, the proportion of inflatable SF6 circuit breakers is relatively large, which will cause damage to environmental protection; there are also circuit breaker switches installed on the column, which can well protect the corresponding loads. It provides protection, but it is not well integrated with the metering system. The metering device is placed in the ground power distribution room or in the switching station. The metering device will formulate different seal standards in each power supply system to prevent electricity theft. Body production, secondary line selection and specification requirements, and acceptance standards for metering cabinets are inconsistent, which makes the product specifications and production methods of equipment manufacturers difficult and cumbersome. Because there are too many measurement standards for lead seals, the production cost of manufacturers increases. , the after-sales work also increases; the workload of the installation company also increases accordingly; the acceptance work is also very cumbersome; the progress and efficiency of the entire project will decrease
