JLS-10Ordinary three (five) column oil immersed high-pressure measuring box supply in stock

Product Overview:

Ordinary porcelain bottles immersed in oilHigh voltage metering boxFor traditional structural products, three column and five column structures are still widely used in power systems. The main body of the transformer is 25 # or 45 # transformer insulation oil, with an accuracy level of 0.2-0.2s. The wide load dual transformation ratio further enhances the excellent characteristics of the product.

Scope of application:

1. This product is suitable for outdoor or indoor complete sets of metering devices in 6-10kV three-phase AC power systems, used for energy metering, especially suitable for power systems with large load peaks and valleys.

2. Usage conditions

a、 Location: Indoor or Outdoor

b、 Environmental temperature: -25 ℃ -40 ℃ Humidity ≤ 90%

c、 Altitude: ≤ 2000 meters

d、 Non corrosive, non flammable, and non explosive gas environment

Technical Specifications:

1. The transformer has good insulation performance and heat dissipation, so the combined transformer has a small volume and electrical performance indicators that meet national standards.

2. Two current transformers of phases A and C, as well as two voltage transformers, are connected in a V/V connection, which are respectively led out by high and low voltage porcelain bushings. The internal structure is tight and firm, with good resistance to thermal stability and dynamic stability performance.

3. The ordinary porcelain bottle oil immersed high-voltage measuring box (five bottles) can be operated with load by changing the transformation ratio and switching the secondary current terminal inside the meter box (but must comply with the "Electricity Safety Operation Regulations").

4. In addition, there are three types of ordinary porcelain bottle oil immersed high-voltage measuring boxes, with three A and three C phase porcelain bushing terminals each. By switching the corresponding terminals and changing the large and small transformation ratios, power must be cut off.

Notes:

1. Installation should be carried out in accordance with the technical requirements of the high-voltage metering box.

2. A set of lightning arresters with corresponding voltage levels must be installed in front of the high-voltage metering box.

3. Pay attention to checking the secondary wiring circuit. The voltage circuit cannot be short circuited, and the current circuit cannot be open circuited.

4High voltage metering box(including the meter box) must be reliably grounded.
