Embodiment 1

[0015] See figure 1 The interlayer insulator rod core for the converter valve valve tower includes a rod core body; one end of the rod core body is provided with threads to form a rod core threaded rod; or both ends of the rod core body are provided with threads to form Two rod-core threaded rods; further comprising a metal connecting end connected to the rod-core threaded rod; the metal connecting end includes a tie rod and a turnbuckle bolt; one end of the tie rod is also provided with threads to form a tie rod threaded rod; The threaded rod is adapted to the flower basket bolt and screwed into the flower basket bolt from the other end of the flower basket; when the flower basket bolt is rotated, the length of the metal connecting end can be adjusted to adjust the valve tower Use the length of the interlayer insulator rod core for fine adjustment. The other end of the tie rod is a cylindrical nut structure.

[0016] As a preferred solution, both ends of the core body 1 are pro...

Embodiment 2

[0019] See figure 1 The interlayer insulator for the converter valve tower includes a rod core and an umbrella disk sleeved on the rod core; the rod core is the same as the interlayer insulator rod core for the converter valve tower in Example 1, so The umbrella plate is sleeved on the core body.

Abstract

The invention provides an interlayer insulator mandril core for a converter valve tower. The mandril core comprises a mandril core body; threads are formed at one end of the mandril core body to form a mandril core thread rod; or threads are formed at the two ends of the mandril core body to form two mandril core thread rods. In addition, the mandril core also includes a metal connecting end connected with the mandril core thread rod; the metal connecting end includes a pull rod and a turnbuckle; a thread is formed at one end of the pull rod to form a pull rod thread rod; and the mandril core thread rod matches the turnbuckle and can be screwed into the turnbuckle from the other end of the turnbuckle. When the turnbuckle rotates, the length of the metal connecting end can be adjusted, thereby realizing fine tuning of the length of the interlayer insulator mandril core for a converter valve tower. In addition, the invention also discloses an interlayer insulator for a converter valve tower. According to the invention, when a converter valve is installed, fine tuning of the length of the interlayer insulator for a converter valve tower can be realized, so that forces exerted on all insulators for converter valve towers become uniform.

Description

Technical field [0001] The invention belongs to the field of high-voltage direct current transmission, and particularly relates to an interlayer insulator and rod core for a converter valve tower. Background technique [0002] The structure of the high-voltage direct current converter valve valve tower basically adopts the suspension type and flexible shock-proof structure design: the valve layers of the valve tower are assembled by multiple interlayer insulators, and the interlayer insulators are fixed on the upper by ordinary bolts. , On the channel steel in the lower valve layer frame, due to the difference in the length of the interlayer insulators, the insulator installation will be more difficult. At present, the length of the interlayer insulators is adjusted in disguise by adding or subtracting spacers on the frame base, thus making the installation The interlayer insulators between the subsequent valve layers bear uniform force. Although this method is feasible, it takes...
