Product Description

Product Description

JLSZW-10W combined transformer (also known as metering box) is composed of voltage and current transformers. The product is used for AC 50HZ, rated voltage below 10KV three-phase line, for voltage, current and energy measurement and relay protection, suitable for urban power grid, rural power grid outdoor substations, and can also be used in various transformer distribution stations in industrial enterprises. Combined transformer with active and reactive watt-hour meters is called a high-voltage power metering box. This product can replace the oil-immersed combined transformer (metering box).
This product can be a combination of a voltage transformer and a current transformer, used to measure single-phase power; it can be a combination of two voltage transformers and two current transformers, used to measure two watts in a three-phase three-wire system The meter method measures three-phase power; it can also be a combination of three voltage transformers and three current transformers for three-phase power measurement. When the transformer is connected, the voltage terminal of the transformer is connected in parallel with the output of the transformer when combined, and the current line of the transformer passes through the combined transformer. The combined transformer is generally used for electric energy measurement in the high-voltage power grid. The combined transformer is the same as the voltage transformer and the current transformer, the secondary output can be connected to the load, but the load should not exceed the nominal rated load of the transformer.

Product features and scope of use

This product consists of a combination transformer and an instrument box.
The combined transformer is composed of two single-phase voltage transformers (PT) and two current transformers (CT). Both PT and CT are electromagnetic, and the two PT windings are connected by V/V to form a three-phase measuring device. , the primary windings of the two CTs are connected in series with the grid A and C, respectively. The side of the box is welded with grounding screws.
The instrument box is connected with the secondary winding outlet of the combined transformer. The instrument box is equipped with a three-phase active watt-hour meter and a reactive watt-hour meter, and the numbers can be clearly read from the inside of the box.
This product is especially suitable for users of medium and small transformers. It can measure active energy and reactive energy completely and accurately. The product design is ingenious and reasonable, the structure is compact, beautiful, and the parts are tightly blocked. device, the instrument box can also be installed separately
Conditions of Use:
This product is used in the range of ambient temperature -30°C~+40°C and below 2500 meters above sea level. The air temperature should not be greater than 85% of the installation site, there should be no serious vibration and turbulence, there should be no strong corrosive gas, and it should not be installed in flammable and explosive places.

Product use and maintenance

Inspection and maintenance before use:
1. Measure the insulation resistance of the winding and compare it with the factory value.
2. Check whether the wiring of the secondary circuit is correct, and whether the position of the junction box screws and the pressure plate is normal.
3. Check whether the grounding of the box shell is good, and whether the lightning protection measures are compromised.
4. When connecting the primary line, it should be consistent with the phase sequence of the power grid, and the incoming and outgoing wiring of P1 and P2 must be correct.
5. The secondary voltage transformer is not allowed to be short-circuited, and the secondary current transformer is not allowed to open. The voltage transformer, the secondary current transformer and the casing must be reliably grounded to ensure the safety of the instrument and personal safety.
