Jls-6 and 10 meter boxes are suitable for the electric energy measurement in the following situations:
A. Rural drainage and irrigation stations, township enterprises, processing plants, small and medium sized factories, mining areas, transportation and other enterprises
Electric energy measurement of high-voltage transmission lines temporarily set up for power supply stations in industrial units and forestry and infrastructure construction sites.
B. Measurement of power generation of small power stations or measurement of power transmission between the power grid of small power stations and the state in connection with the operation of the network.
2. Environmental conditions:
2.1 the altitude shall not exceed 1000m;
2.2 ambient temperature:
High + 40 ℃;
The average no more than 30 ℃;
Low - 25 ℃;
2.3 system grounding: neutral non-effective grounding system;
2.4 atmospheric conditions: there is no serious pollution in the atmosphere.
Usage and precautions:
5.1 this product can be measured if it is used to measure the power of branch lines or when it is used to assess the line loss
The box is mounted on the bracket of the pole.
5.2 when measuring the power transformer's high voltage side power, it can be installed on the same platform or installed on the same platform as the transformer
On the pole.
5.3 when the meter box in the new installation and operation is found to have opposite phase sequence, the active power meter will still turn forward and reactive power will appear
When the meter is reversed, the meter is wrong, and any two of the high-voltage side of the meter box should be replaced
Change into positive phase sequence to ensure accurate measurement of the meter box.
5.4 when the product is used to measure the electrical degree of power lines in two phases and one place, the ground shall be connected to the B phase of the meter box, and the rest
The two phases are connected in a positive phase sequence to prevent additional measurement errors.
5.5 the product must be hoisted by the oil tank.
5.6 the secondary terminal b of the combined transformer and the grounding bolt on the fuel tank shall be reliably grounded to avoid accidents
6. Maintenance and custody:
Or new oil.
6.2 metering box before use to properly keep in the warehouse, the warehouse temperature is 25 ℃ to + 40 ℃, the relative
Humidity not more than 85%, good ventilation, non - corrosive gas presence.
7. Ordering instructions:
Please specify the following items when ordering this model.
7.1 product model;
7.2 rated voltage ratio;
7.3 rated current ratio;
7.4 accuracy level;
7.5 product use environment;
