This kind of switch applies to single-phase, three phase , combinationoil-imersed transformer electrical power with frequency of50HZ, , 60HZ, ratedvoltage of 10KV,35KV,rated current of 30A500A; the voltage-regulating mode are.central part, terminal pointneutral point, which can be directly fixed on the tankcover of the transformer,exchange under the off-circuit condition.
Function
1. The primary coil voltage of the transformer is regulated in the American box type transformer, without the need to open the cover after powering off, to ensure the safety of operation and maintenance;
2. Adapt to oil immersed distribution transformers to avoid contamination inside the oil tank;
3. Cooperate with transformers of different capacities (≤ 1500kVA) to achieve voltage gear switching
Feature
Compact adaptation: Small modular design with built-in fuel tank, compatible with the compact layout of American style gearbox
Non excitation safety: power outage voltage regulation, avoiding the risk of arc short circuit, low operating threshold
Sealed weather resistance: Fully sealed structure, corrosion-resistant and oil resistant, suitable for harsh outdoor environments
Reliable contact: Silver alloy contacts, gear locking, no loose or incorrect switching
Low operation and maintenance costs: simple structure, low maintenance volume, and much lower cost than on load switches
