Abstract

The invention discloses an automatic metering device for a distribution transformer, which relates to a local or remote power distribution management system, in particular to an automatic metering device installed inside a distribution transformer, which includes a voltage transformer, a current transformer, a high-voltage capacitor Voltage regulator, suspended power supply unit, metering unit, distribution parameter monitoring unit, wireless transmission unit. The invention realizes the metering of the primary side of the distribution transformer. Since the automatic metering device of the distribution transformer realizes the metering of the secondary side of the distribution transformer at the same time, the variable loss of the distribution transformer can be calculated, thereby significantly improving the monitoring and management of the distribution transformer. Level, and can also be easily applied to the remote power distribution management system.

Description

technical field [0001] The invention relates to an automatic electric energy metering device installed inside a distribution transformer, in particular to an automatic electric energy metering device installed inside a distribution transformer to realize primary side and secondary side electric energy metering, distribution transformer operating condition monitoring and has a wireless Metering device with data transmission function. It can be applied to electric energy metering, distribution transformer operating parameter monitoring and distribution transformer line loss calculation. Background technique [0002] At present, the electric power department implements electric energy metering and distribution condition monitoring indirectly through the distribution back-end equipment outside the distribution transformer. Inaccurate measurements etc. In short, the existing electric energy measurement and collection of distribution transformer working status are indirect, or n...
