Embodiment Construction

[0010] Such as figure 1 As shown, taking the CMD-type on-load tap-changer structure as an example, the on-load tap-changer bracket of the present invention is an independent structure, located on one side of the transformer clip 3, including bolts connected to both sides of the on-load tap-changer 2 Two vertical splints 1, the vertical splint 1 is perpendicular to the transformer clamp 3, the bottom of the two vertical splints 1 is connected with a horizontal support plate 4, and the outer side of a vertical splint 1 close to the transformer clamp is connected with a fixed plate 6, the fixed plate 6 It is connected with the transformer clamp 3 by bolts. The operating rod 5 is located on the upper part of the on-load tap-changer 2, thereby not only avoiding the operating rod 5, but also making the support of the on-load tap-changer more stable and clamped more firmly.

[0011] The above-mentioned embodiments are used to specifically illustrate this patent. Although the text is...

Abstract

The invention discloses a novel on-load tap changer bracket for a transformer. The on-load tap changer bracket is positioned on one side of a transformer clamp, and comprises two vertical clamping plates which are connected with the two sides of the on-load tap changer through bolts respectively, wherein the vertical clamping plates are perpendicular to the transformer clamp; the bottoms of the two vertical clamping plates are connected with a cross supporting plate; and the vertical clamping plates are connected with the transformer clamp. The bracket has the advantages that: a disassemble structure is adopted by the bracket, a clamping arm of the on-load tap changer bracket is away from an operating rod of the on-load tap changer by changing the clamping direction of the on-load tap changer bracket; and the bracket is more stable and the clamping is firmer by arranging the supporting plate.

Description

technical field [0001] The invention relates to a novel on-load tap-changer support for transformers, in particular to the support for on-load tap-changers for CMD, MD, SHZV and other transformers. Background technique [0002] At present, with the development of the power system and the progress of science and technology, the transformer on-load tap-changer has also added new models such as CMD, MD, and SHZV from the original ordinary M type. Due to the movement of the joystick of the new switch, the original old switch bracket collided with the joystick and could not be installed. Contents of the invention [0003] In order to solve the above technical deficiencies, the present invention provides a new type of on-load tap-changer support for transformers that can be disassembled, has a reasonable design, and will not collide with the operating rod of the on-load tap-changer. [0004] The present invention is achieved through the following measures: [0005] The present...
