Abstract
The utility model relates to the class of electricity transmission and distribution devices, more specifically to a supporting insulator for cable outdoor terminals. The utility model is composed of a screw rod, supporting insulators, a bracket, etc. The utility model is characterized in that the upper end L2 of the screw rod is lengthened; compared with the lower end L1, L2 is longer than L1; the upper end L2 of the screw rod is screwed with a nut; a terminal bottom plate is installed on the four supporting insulators which are screwed with nuts; the nuts are adjusted to enable the four corners of the terminal bottom plate to be on the same horizontal plane. The utility model is suitable for cable outdoor terminals with high voltage more than 66KV.
Description
One, technical field:
The utility model relates to a kind of equipment for power transmission and distribution class, more specifically is meant the supporting insulator of cable outdoor terminal, and it is one of main structural components of cable outdoor terminal equipment, mainly is applicable to 66KV and above high-tension cable outdoor terminal.
Two, background technology:
The installation method of cable outdoor terminal equipment is normally earlier rack-mount with four supporting insulators, then the associated components of installing terminal on supporting insulator.Terminal support generally adopts the angle steel welding, and four holes of support mounting plane customization can not be in same plane, and the length of four supporting insulators also can not be identical.Therefore traditional common supporting insulator is installed on conventional bracket, and the terminal base plate can only have triangle to be in same plane for four jiaos, and another angle will be in unsettled state.Terminal will be in a kind of unsettled stress like this, and the angle between terminal base plate plane and the horizontal plane is uncontrollable, and insulator is difficult to accomplish vertical installation.
110KV cable termination insulator length is 130mm and 220KV cable termination insulator length reaches 2200～2600mm, to large-sized like this porcelain bushing, if can not vertically install, is disadvantageous certainly to the long-term stability operation of terminal.
Three, summary of the invention:
Key problem in technology to be solved in the utility model is for outdoor terminal provides desirable horizontal mounting surface the terminal porcelain bushing vertically to be installed, and lower stress is desirable more in working order thereby make terminal, helps the long-term stability operation of terminal.
For this reason, the utility model carries out design improvement to supporting insulator, and upper end screw rod lengthening screws in a nut respectively earlier before the terminal base plate is installed, and then on four nuts the installing terminal base plate.So at the construction field (site), can regulate the position of four nuts under the base plate by the workmen according to actual conditions, four jiaos that guarantee the terminal base plate on same plane, the defective of having avoided common supporting insulator to bring is farthest guaranteed the stability of terminal.
Four, description of drawings:
Fig. 1 is the utility model structural representation
Fig. 2 be the local scheme of installation in outdoor terminal bottom in Fig. 1: 1 screw rod, 2 post insulators, 3 supports.In Fig. 2: 2-1 supporting insulator, 2-2 nut, 2-3 base plate, 2-4 insulator.
Five, embodiment:
With reference to the accompanying drawings 1: the utility model is by screw rod 1, post insulator 2, and support 3 is formed, existing upper end L with screw rod 1
2Lengthening, and lower end L
1Remain unchanged, i.e. L
2＞L
1
With reference to the accompanying drawings 2, before terminal base plate 2-3 installs, screw in a nut 2-2 respectively earlier in the upper end of supporting insulator screw rod 1, and then on four nuts installing terminal base plate 2-3.When constructing at the scene, can regulate four nut 2-2 under the base plate 2-3 by the workmen according to actual conditions, guarantee that four jiaos of terminal base plate 2-3 are in same plane, the defective of avoiding common supporting insulator to bring is like this farthest guaranteed the stability of terminal.The utlity model has following advantage:
1. guarantee the installation of terminal support level, the terminal insulator can vertically be installed, lower stress is desirable more in working order thereby make terminal, strengthens the long-time stability of terminal.
2. on different terminal supports, can realize vertically arranged consistency.
3. simple in structure, easy for installation.
