Embodiment Construction

[0010] A dry-type high-voltage metering box, which is an outdoor dry-type two-element type, is suitable for 50Hz, 15-20kV three-phase AC power lines or distribution transformers, and a double-ratio metering box is selected, equipped with a current transformer and a Voltage transformer, using V / V wiring, rated secondary current 5A, rated secondary voltage 100V, equipped with three-phase three-wire active or reactive energy meter, for power users with large seasonal load changes, double transformation ratio can be selected Wide range and limited high-voltage metering box, without power failure, the transformation ratio can be reversed by changing the connection plate of the special transformer terminal box in the meter box. The meter box and combined transformer can be connected in one piece to form a conjoined high-voltage metering box, which can be installed and used on the column. ; It can also be installed separately, the combined transformer is installed on the column, the m...

Abstract

A dry-type high-pressure metering box is an outdoor dry-type two-element metering box and suitable for a 50Hz 15-20kV three-phase alternating current power line or a distribution transformer. By using the double-transformation-ratio wide-quantitation-limit high-pressure metering box, the transformation ratio is switched in the metering box by changing a special mutual inductor terminal box connecting piece without power outage, a meter box is integrally connected with a combined mutual inductor to form the one-piece high-pressure metering box, the meter box and the combined mutual inductor are installed and used on a column or respectively installed. When the meter box and the combined mutual inductor are respectively installed, the combined mutual inductor is installed on the column, and the meter box is installed under the combined mutual inductor and connected with the combined mutual inductor through a sheathed cable. The problem that an existing high-pressure metering box is high in failure rate and short in service life and is easily lost and stolen is solved.

Description

technical field [0001] The invention relates to a dry-type high-voltage metering box, which belongs to the technical field of electric power equipment. Background technique [0002] The high-voltage metering box is mainly used for high-voltage electric energy metering, especially suitable for medium and small transformer users. It can measure active and reactive energy completely and accurately. It is equipped with a meter box to form a complete metering device, and the meter box can also be installed separately. The existing high-voltage metering box has a high failure rate, a short service life, and is easy to be stolen. Contents of the invention [0003] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0004] A dry-type high-voltage metering box, which is an outdoor dry-type two-element type, is suitable for 50Hz, 15-20kV three-phase AC power lines or distribution transformers, and a d...
