33kV - 1600kVA Cast Resin Dry Type Transformer, Three Phases, Power
Features & Advantages
The epoxy resin casting dry-type transformer manufactured by Pearl
Electric is a type of transformer with low noise, low loss and low
partial discharge. With excellent structure, superior materials,
scientific design, strict production technology and advanced
testing method, the transformer also has the following advantages:
1. Self-extinguishing and inflaming retarding, fire-proof and
explosion-proof, pollution-free and no toxic gas being generated.
2. Excellent damp-proof performance, capable of working under 100%
relative humidity and other harsh conditions, with no damp-removing
3. Thin resin structure realizes chap-free surface and excellent
4. Great overload capability, capable of operating continuously
under 110% overload conditions and in case of air forced cooling,
operating continuously under150% overload conditions.
5. Nice appearance, small-size, less installation space occupation
and low engineering cost.
6. Each performance index and technical specification excels those
specified in China GB, international IEC or industrial standards.
Supply Disconnection / Reconnection
The direct connected meter shall be fitted with disconnection &
reconnection unit, to provide remote disconnection &
The status of the contactor of the meter shall be displayed on the
Contactor shall operate in following modes:
- Automatic: In this mode, reconnection is made instantly on
receiving a proper command from Central Station, without any action
on the meter (with security at software level).
- Manual: In this mode Central Station will send a command, only to
allow reconnection. But the actual reconnection can be done only
after pressing a push button on the meter or on a Customer Display
Unit after ensuring the safe reconnection. This feature is to
ensure maximum safety of the customer.
The contactor shall be rated at or above the maximum rating of the
meter to carry the maximum rated current of the respective type of
The main supply contactor shall be rated to carry the required
maximum current per phase, continuously at the rated voltage, and
have a minimum life of 10,000 switching operations at full rated
The meter shall give clear indication when the supply has been
disconnected to limit the power demand.
The latch shall not be accessible to and operable by the customer.
The contactor is to be stable and in the event of an interruption,
on subsequent restoration of the mains supply, the contactor state
shall remain unaltered.
