Embodiment Construction

[0022] A device for removing a thyristor of a converter valve according to the present invention will be described in detail below with reference to the drawings and embodiments.

[0023] Such as figure 1 and 2 As shown, a dismantling device for a thyristor of a converter valve according to the present invention includes a support beam 2 and a set of expansion blocks 1, and the support beam 2 and the expansion blocks 1 are independent of each other. Such as image 3 and 4 As shown, the support beam 2 is an aluminum beam with a triangular cross section, which makes the structure lighter. On its facade, there is a round hole at the end, which is fixed on the base 5. The horizontal surface of the support beam contacts the bottom surface of the radiator 4, and after the pressure-fitting force is removed, the support beam plays a role in supporting and positioning the radiator. Such as Figure 5 and 6 As shown, the expansion block 1 is composed of a left-handed stud 1.1, a r...

Abstract

The invention relates to a detaching device for a thyristor of a converter valve, which comprises a support beam and two sets of unfolding blocks, wherein the unfolding blocks comprise left and right screw bolts and double screw nuts; the end parts of left and right screw bolts are of stair-shaped structures; thread holes which are arranged on the upper sides of the end faces are matched with the thread holes on a radiator; the screw bolts can be fixed on the radiator of the thyristor; the left and right screw bolts are provided with outer threads; and two sides of the double screw nuts are respectively provided with inner threads. When the detaching device is used, the radiator can be unfolded and the thyristor can be taken off, only by rotating the double screw nuts. The detaching device has simple structure. The auxiliary equipment required by the detaching process is less. The detaching device is conveniently used, is time- saving and labor-saving, and is safe and reliable.

Description

technical field [0001] The invention belongs to an electric power system, and in particular relates to a dismantling device for a thyristor of a converter valve. Background technique [0002] In the power system, the converter valve is a very important DC power transmission and transformation equipment, and the thyristor is the core component of the equipment. In the converter valve, several thyristors and thyristor radiators are pressed together under great pressure to form a thyristor press-fit integrated TCA unit (TCA, Thyristor Clamp Assembly TCA is the abbreviation of thyristor press-fit integration). With the development of thyristor technology in power electronics technology, the diameter of thyristor has increased from 5 inches to 6 inches. Large diameter thyristors have strong flow capacity, but they require greater pressing force. The greater the pressing force of the thyristor, the higher the requirements for the removal tool. At present, the related equipment m...
