Problems solved by technology

However, in recent years, the rod-type bushing has caused many major problems in the power system, causing transformer explosions, fires, and system shutdowns.
[0003] Investigations and studies have shown that due to thermal expansion and contraction of the tie rod system itself, the tension will change, which will lead to the loosening of the bushing rod system and the terminal block, making the connection between the current-carrying bottom plate and the terminal block loose, causing discharge at the bottom of the bushing The arc is drawn, a large amount of gas is generated, and finally the transformer bushing is discharged, causing the internal fault of the transformer

Embodiment Construction

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0025] like figure 1 with figure 2 As shown, the present embodiment disclosed, a converter variable web side sleeve tube rod system, including a cylindrical tie rod 1, and the pulley 1 consists of three sets of struts, and the tie rod 1 is made of steel, the length of the lever 1 is 7278mm; the bottom of the pulley 1 is connected to the wiring device 6, and the top of the tie rod 1 is connected to the fixing device 9, and the fixing device 9 includes a detachable cap 91 and a top nut 92; the bottom fixing of the fixing device 9 is fixedly connected to the aluminum tube 2 The compensation of the aluminum tube 2 is set in the periphery of the tie rod 1, and the height of the aluminum tube 2 is 3308 mm.

[0026] The top of the wiring device 6 is uniformly mounted along the circumference, and the inner side surface of the carrier base plate 3 is fixedly co...

Abstract

The invention relates to a bushing pull rod system on the converter grid side, comprising a pull rod, the bottom of the pull rod is connected with a wiring device, the top of the pull rod is connected with a fixing device, and the bottom of the fixing device is connected with a vertical compensation aluminum tube; the wiring device A current-carrying bottom plate is arranged on the top of the current-carrying bottom plate, and a positioning compensation tube is connected to the current-carrying bottom plate. The aluminum pipe is in contact with the compensation steel pipe. By adopting the above technical scheme, the current-carrying base plate and the wiring device are combined more closely, and the loosening of the tie rod and the wiring device caused by the thermal expansion and contraction of the tie rod itself is reduced, so that the tie rod system is more stable and the internal occurrence of the transformer is reduced. possibility of failure.

Description

Technical field [0001] The present invention relates to the technical field belonging to high pressure maintenance, and in particular to a converter variable web side casing tie rod system. Background technique [0002] Change variable web side sleeves typically have a guide type, cable-on-line and tie, where the rod sleeve is widely used in the power system due to facilitating transportation and installation. However, in recent years, the tensioning casing has caused many major problems in the power system, causing transformer explosions, fire, system shutdown, etc. [0003] The investigation and research showed that in the tensile system itself causes the pulley to cause the pulley to change, thereby causing the sleeve tie rod system to loosen, so that the connection between the carrier bottom plate and the terminal block is loose, causing the bottom discharge of the sleeve. Scales, generate a large amount of gas, eventually trigger the transformer sleeve discharge, causing int...
