The THT-ZT transformer neutral grounding resistor cabinets are
applicable to the transformer neutral points of 6~35KV AC power
grids to achieve the neutral point grounding via resistor
1) resistor+current transformer+cabinet
This case is suitable for transformer has neutral point
2）resistor+current transformer+three-phase grounding transformer
This case is suitable for transformer doesn’t have neutral point,we
need provide a neutral point via three-phase
1)cabinet material : stainless steel plates or hot dip Al-zn coated
steel or cold-rolled steel plates;the degree of
protection of cabinet is from IP32 to IP55.
2)according to installation we can provide indoor or outdoor
3)The current transformer in resistor cabinet can measure the
grounding fault current and lead to the relay
protection device that setting circuit breaker tripping time
according to the grounding fault current.
4)We can equip counter for recording number of grounding that can
be installated on the observation window of
5)There have four lifting rings on the top of cabinet and four
trapezes at the bottom of cabinet that can be easy
to lift at shipping and installation.
6)The demension of cabinet outline is determined by detail
parameters from customer.
