Abstract

A high voltage thyristor valve of the air insulation type erected upright on a valve hall is disclosed, which comprises a thyristor valve body erected in the valve hall and a plurality of reinforcing means stretched between the thyristor valve body and inner walls of the valve hall, each of the reinforcing means including a wire rope and an insulator.

Claims

1. A high voltage thyristor valve accommodated in a valve hall, comprising:

a thyristor valve body having a tower-like multiple-valve structure erected upright on the floor of said valve hall; and

at least two reinforcing means, each being stretched between said thyristor valve body and an inner wall of said valve hall and including a wire rope and an insulator for reducing vibrational stress to the thyristor.

2. The high voltage thyristor valve according to claim 1, wherein:

said reinforcing means further includes a shock absorber with a spring.

3. The high voltage thyristor valve according to claim 2, wherein:

said shock absorber further includes a damper.

4. The high voltage thyristor valve according to claim 1, wherein:

said reinforcing means further includes a turnbuckle for adjusting the length thereof.

5. The high voltage thyristor valve according to claim 1, further comprising:

spring means provided between a lower end of said thyristor valve body and the floor of said valve hall.

6. A high voltage thyristor valve accommodated in a valve hall, comprising:

a plurality of valve bodies, each having a tower-like multiple-valve structure erected upright on the floor of said valve hall;

a plurality of reinforcing means, each being stretched between said thyristor valve body and an inner wall of said valve hall and including a wire rope and an insulator for reducing vibrational stress to the thyristor; and

coupling means stretched between adjacent two said thyristor valve bodies and including a rope.

7. The high voltage thyristor valve according to claim 6, wherein:

said reinforcing means further includes a shock absorber with a spring.

8. The high voltage thyristor valve according to claim 7, wherein:

said shock absorber further includes a damper.

9. The high voltage thyristor valve according to claim 6, wherein:

said reinforcing means further includes a turnbuckle for adjusting the length thereof; and

said coupling means further includes a turnbuckle for adjusting the length thereof.

10. The high voltage thyristor valve according to claim 6, further comprising:

a plurality of spring means, each provided between a lower end of each of said plurality of thyristor valve bodies and the floor of said valve hall.
