What is the general size of neutral grounding resistance cabinet?
Resistance cabinet? Dimensions are generally designed according to the parameters required by customers, such as specific parameters such as resistance and heat dissipation. Generally speaking, they are not exactly the same size.
1. This series of products are made of imported stainless steel alloy, with low temperature rise coefficient and small resistance change rate.
2. Double insulation of ceramics and mica is adopted, which has high stability.
3, bolt connection, convenient disassembly and reliable connection.
4. Unique steel grating structural design: convenient for heat dissipation;
5. The resistor has large heat capacity: the rated power of a single resistor can reach 1200 watts through unique processing technology;
6. Small resistance deviation: the manufacturing tolerance of resistance can be less than 5%;
7. The resistance of the resistor can be adjusted in a wide range: the single chip range is 0.005 ~11.7 Ω;
8. The resistance sheet has strong insulation performance: the resistance bar and bracket can withstand the voltage up to 8.3KV; ;
9. The change rate of hot resistance is small: the resistance is made of imported stainless steel with low temperature coefficient, and the change rate of hot resistance cannot be higher than 20%;
10, strong vibration resistance: the resistors are connected by stainless steel bolts, which has strong vibration resistance;
1 1, strong corrosion resistance: the resistor is made of high-temperature alloy material, which has strong corrosion resistance;
12, high cost performance: compact structure, adjustable number of resistors, high cost performance.
13, which can be matched with intelligent monitoring device, can effectively monitor grounding fault current and voltage, and provide switching value and alarm contact.
