The utility model is characterized in that the combined mutual inductor is formed by the connection of two current transformers, two voltage transformers, a primary conductive wire, and a conductive rod which are encapsulated into a whole by insulating resin and are arranged on a mounting board in the box body; a secondary conductive wire of the combined mutual inductor is connected with the input ends of an active electricity meter, a reactive electricity meter, and a discharging recording device which are arranged below the box body forming a metering device by a wire connecting terminal.
Description
The utility model relates to the totally-enclosed full-insulating high-voltage electric power of a kind of dry type electrical energy metering tank, belongs to High-voltage measuring box or metering cabinet class.
Be used for the 10KV High-voltage measuring box that rural power, small power station and part city net electricity use at present in the power industry, great majority adopt the oil-immersed self-cooled structure.Therefore exist problems such as inflammable, explosive medium and transformer oil seepage.Not only influence safe operation, nor the easy care maintenance.
The purpose of the present utility model: be to provide the totally-enclosed full-insulating high-voltage electric power of a kind of dry type electrical energy metering tank; Wish that it can overcome the number of drawbacks of above-mentioned oil immersed type batch meter, to adapt to the needs of current rural power, water power and urban distribution network safe and highly efficient operation.
The foregoing invention purpose, realize by following technological approaches:
The totally-enclosed full-insulating high-voltage electric power of this dry type electrical energy metering tank, form by casing (3), high-tension porcelain insulator (2), combination transformer and measuring instrument, it is characterized in that described combination transformer is connected with conducting rod (1) with a voltage transformer (VT) (14) and other a lead by two current transformers (5) respectively, and it is packaged into one, and be placed on the installing plate (13) in the casing by insulating resin (4); The secondary lead (7) of this combination transformer links to each other with the input end of being located at casing below, the power electric meter (8) of forming measuring instrument, idle ammeter (9), discharge counter (12) by connection terminal (6) simultaneously.
The iron core of described current transformer (5) and voltage transformer (VT) (14) is the ring-type iron core.
The described metering only casing of matrix section is provided with combination padlock (11).
According to the totally-enclosed full-insulating high-voltage electric power of the dry type of above conceptual design electrical energy metering tank, compare with at present general oil-immersed and high-voltage electric power electric power meter, its advantage is: owing to adopt ring-type iron core and dry construction, the overall volume and the weight of device are reduced greatly, and its magnetoconductivity open circuit loss is greatly reduced, reach more than 0.2 grade, simultaneously owing to adopt all-sealed structure, not only do not have seepage, improve safety in utilization yet; In addition owing to disposed measuring instrument, thereby also improved the accuracy of measuring.
