Intelligent monitoring device for high-voltage electrical energy

Abstract

The invention relates to an intelligent monitoring device for high-voltage electrical energy, which is used for comprehensive power distribution and metering of high-voltage metering in a power distribution network. The device mainly comprises a high-voltage electricity-operated circuit breaker (1), a high-voltage metering box (2), an electronic three-phase multifunctional electric energy meter (3), a safeguard door lock switch (4), a remote automatic control terminal (5), a power supply computer (7), an electricity manager mobile phone (8) and a mobile communication base station (9), wherein the power supply computer (7) is connected with a bidirectional communication module (6); the power of the high-voltage electricity-operated circuit breaker (1), the electronic three-phase multifunctional electric energy meter (3) and the remote automatic control terminal (5) are taken from a 1,000VA-uninterrupted power supply (UPS) (18) with long time delay; the input end of the 1,000VA UPS is connected with a 220V / 1200VA-voltage transformer (19) through a voltage surge absorbing circuit (21); the high-voltage end of the voltage transformer (19) is connected with a lightning protection device (20). The intelligent monitoring device for the high-voltage electrical energy can perform long-distance data transmission and perform timely and reliable monitoring and metering on power supply situations.

Description

technical field [0001] The invention relates to a high-voltage metering integrated power distribution device used in power distribution networks, in particular to an intelligent monitoring device for high-voltage electric energy. Background technique [0002] At present, most of the electric energy metering integrated distribution devices used in the power supply and distribution system are low-voltage metering integrated distribution devices designed and manufactured by traditional manual meter reading methods. In the actual operation of the low-voltage metering integrated distribution device, there are certain irrationality, for example, the no-load power loss of distribution transformers is calculated into the actual power consumption of power consumers by using artificially estimated values. Dispute with electricity supply department. Also because the existing high and low voltage metering devices do not have the remote automatic control function, there are certain defe...

Problems solved by technology

Once the high-voltage line transmission fails, the remote automatic control terminal and the electric knife switch of the high-voltage electric circuit breaker will lose power. At this time, all communication and control functions, the anti-theft alarm function will disappear, and the high-voltage electric circuit breaker The electric knife switch of the switch lacks reset power; the computer of the power supply station, the mobile phone of the electrician, and the mobile communication base station also lost control of the power distribution device at the place
