Abstract
The utility model discloses a mini-type measurement device for indoor high voltage electricity power, which consists of an insulation shell with a mutual inductance arranged inside or outside the insulation shell, and three shielding boxes inside the shell. The shielding boxes are provided with high voltage measurement circuit modular, which are interconnected with fiber. The utility model is condense in structure, minimal in type, low in cost, and with advanced capacity of solid insulation wear, which weighs only 5 kg, and can achieve 0.5 S class electricity power measurement accuracy, is thereof very suitable for application in measurement tank with highly condensed solidity requirement.
Description
Technical field
The utility model belongs to electric power meter, is specifically related to a kind of high-tension line (10kV and above grade) direct measuring apparatus of primary side monoblock type, is particularly suitable for using the compact volume applied environment in 10kV or 35kV loop-network switch cabinet.
Background technology
The urban and rural power grids of the present 35kV of China, 10kV electric pressure, all are isolated neutral systems, adopt of the high-pressure side metering of high pressure measurement device, be generally the Vv mode of connection, insert three-phase three-wire electric energy meter by two groups of electric energy sampling units and measure at user's substation transformer.What generally use is the high-voltage power metering device, and it comprises: metering voltage, current transformer, electric energy meter, the secondary circuit between mutual inductor and the electric energy meter, electrical energy metering tank or electric energy metrical cabinet etc.
In urban distribution network, be generally the form of electric-power metering cabinet,, adopted metal materials such as more insulating material and copper iron owing to need to solve the primary side of voltage transformer (VT) summation current transformer and the High-Voltage Insulation problem of secondary side, on volume, be difficult to dwindle, structurally be difficult to simplify.Thereby existing power metering cabinet and traditional high-voltage power metering device are set of equipments that resource consumption is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of indoor type high-voltage electric power meter of small size, to overcome above-mentioned defective.
The technical solution of the utility model is: small size indoor type high-voltage electric power meter, it comprises insulation shell, in the insulation shell or the mutual inductor of insulation shell peripheral hardware, establish three shielding box bodys in the housing, establish the high-voltage electric energy measurement circuit module in the shielding box body, the high-voltage electric energy measurement circuit module that will be shielded in the box body by optical fiber between the shielding box body connects.
This device has that compact conformation, volume are little, only 5 kilograms of weight, saves metal consumptions such as a large amount of insulating material and copper iron, and cost is lower; Adopt solid insulation, do not have oil, no gas, do not have the hidden danger of seepage or leakage, the not high simplified manufacturing process that makes of seal request, integral insulation reliable durable.The electric energy metrical precision reaches the 0.5S level, is highly suitable for the application demand of compact volume in the metering cabinet.
