Remote meter reading device applied to reactive field compensation of agricultural irrigation motor-pumped well and system of remote meter reading device

Abstract

The invention discloses a remote meter reading device applied to reactive field compensation of an agricultural irrigation motor-pumped well and a system of the remote meter reading device and relates to the technical field of devices for metering and reactively compensating electric energy. The remote meter reading device comprises an intelligent prepayment electric energy meter, a compensation capacitor switching on-off switch, a compensation capacitor, a carrier communication module, an electric leakage protector and a relay. The device is capable of achieving reactive field compensation of the agricultural irrigation motor-pumped well submersible pump and remotely reading information of the electric energy meter of the agricultural irrigation motor-pumped well submersible pump, and is stable to run and convenient to use, and line loss is reduced.

Description

technical field [0001] The invention relates to the technical field of electric energy metering and reactive power compensation devices, in particular to a remote meter reading device and a system thereof for on-site reactive power compensation of agricultural irrigation machine wells. Background technique [0002] After the transformation of the power grid and the improvement of the rural power grid, the agricultural drainage and irrigation grid has been significantly improved, but the capital investment in the power supply construction of the agricultural drainage is relatively small, the power supply capacity is insufficient, there are potential safety hazards, the phenomenon of estimated copying and missing copying is common, and electricity prices are apportioned outside the country, etc. The problem has become the focus of agricultural power enterprises, mainly in the following aspects: [0003] (1) The construction cost is high. First, 0.4kV voltage is used for agric...

Problems solved by technology

[0004] (2) Agricultural drainage and irrigation meters are difficult to manage. Most meters still use manual meter reading, which is labor-intensive and inefficient, resulting in a great waste of manpower, material resources and time; Problems such as copying, missing copying, wrong copying, miscalculation, and long meter reading cycle, let alone the prevention and control of electricity theft, and some places have to implement contracted line loss, which has become a blind spot in metering management and line loss management of county-level power supply enterprises and difficulty

[0005] (3) Low safety factor
