Abstract

The utility model relates to a grounded shield structure, which is used for a grounded shield between a high-voltage coil and a low-voltage coil applied in a transformer and an electric reactor, and belongs to the technical field of the transformer and the electric reactor. According to the technical scheme, the grounded shield structure comprises the low-voltage coil (4), the high-voltage coil (5), a ground lead (1) and the grounded shield (6); the grounded shield is arranged between the low-voltage coil and the high-voltage coil; and the grounded shield is grounded through the ground lead. The grounded shield structure has the beneficial effects that the grounded shield is arranged between the low-voltage coil and the high-voltage coil so as to avoid the insulation damage of the low-voltage coil caused as a lightning surge overvoltage existing in a high voltage is transferred to the low-voltage coil with a lower insulation level, and further, the shield is grounded for shielding the generation of the transferred overvoltage so as to protect the insulation of the low-voltage coil.

Description

A kind of earth shield structure
Technical field:
The utility model relates to a kind of earth shield structure, is used for the high pressure that transformer, reactor use, the earth shield between the low-voltage coil, belongs to transformer, reactor technical field.
Background technology:
At present, at extra-high voltage transformer or exist in the shunt reactor of low-voltage coil, do not have the earth shield structure that is suitable for, the lightning impulse overvoltage that in high pressure, exists to be delivered to the lower low-voltage coil of insulation level and cause the insulation damages of low-voltage coil.
The utility model content:
The utility model purpose provides a kind of earth shield structure, is used for shielding transmitting superpotential generation, with the insulation of protection low-voltage coil, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: a kind of earth shield structure, comprise low-voltage coil, high-tension coil, ground lead, earth shield, and between low-voltage coil, high-tension coil, earth shield is set, earth shield is by ground lead ground connection.
