220KV Transformer Gap Discharger Manufacturer Transformer Neutral Protection

Product Overview:

110KV and 220KV is the main voltage grades in power supply grid, due to high voltage the neutral point usually grounds solidly or some of neutral point of transformers does not ground based on requirements of relay setting and avoiding communication interference for limiting single-phase short-circuit current. By this way, the neutral point would be overvoltage caused by lightning stroke or single-phase grounding faults. Moreover most transformers are graded insulation, so the the overvoltage hazards to neutral insulation is huge. We must set a protective device preventing such accidents from occuring. MRD-NP transformer neutral gap protector of our company is such a device for it. It is produced strictly as per DL/T620-1997 overvoltage protection and insulation co-ordination of AC electrical equipments, applicable to 110 kv and 220kv power system where transformer neutral point does not ground.

Product Features:

1. With advantages of full-function, small cubic, high reliability and easy-installment, MRD-NP type transformer neutral point gap protective device is a combined equipment integrating electrical equipments like isolated switch, zinc oxide arrester, discharging gap, current transformer etc.

2. MRD-NP type transformer neutral point gap protective device has two types i.e. club-shaped gap and spherical gap.

3.Arrester and disconnector could match on flexible base and disconnector could be mannual or moter driven depending on project requirement.

4. Gap diacharging voltage is stable and the gap is easy to adjust.

5. Electrode is finish-machined by pure copper or high strong stainless steel.

6. Installing hole is made at the bottom of device, suitable for transportation hoisting and installment on site.

7. When installing on site, the mounting bracket could adopt seamless steel tube with high strength ensuring bracket stability.
