Abstract
The utility model relates to the technical field of combined electric equipment, in particular to a telescopic conducting rod of a 252kV combined electric device. The telescopic conducting rod comprises a conducting pipe, wherein the conducting pipe is in sliding connection with the telescopic conducting rod, a strip-shaped contact is arranged on a connecting region of the conducting pipe and the conducting rod and is fixedly connected to the conducting pipe, a screw rod is arranged on the conducting pipe, and a hole is formed on the conducting rod and is matched with the screw rod. The telescopic conducting rod has the characteristics of simplicity, practicality, high reliability, easiness for field test and the like.
Description
Technical field
The utility model relates to a kind of technical field of combined electric appliance equipment, the telescopic conducting rod of specifically a kind of 252kV combined electrical apparatus.
Background technology
At present, the 252kV combined electrical apparatus is popularized and is come in province, city's electric power system, has a lot of enterprises also to begin a large amount of uses.Along with the continuous increase of demand, market competition is still fierce, and manufacturing sector begins to be conceived to the control of production cost, seeks new material, new technology, improves the quality of products, and optimizes product structure.Concerning the combined electrical apparatus product, be the manufacturing cost that reduces parts on the one hand; Be exactly to shorten workshop and on-the-spot built-up time on the other hand, improve installation effectiveness.
Design in the past; Mostly the connector of this structure middle and lower part is lightning arrester or voltage transformer (the combined electrical apparatus standard-required can not have lightning arrester and voltage transformer etc. when industrial frequency withstand voltage); The conducting rod that is attached thereto is a single piece, and not flexible is not so installed earlier similar lightning arrester, voltage transformer etc. before withstand voltage in the past; Withstand voltagely install after qualified, workload is big again.
Summary of the invention
The purpose of the utility model provides the telescopic conducting rod of a kind of 252kV combined electrical apparatus.
The technical scheme that the utility model adopts is: the telescopic conducting rod of 252kV combined electrical apparatus; Comprise the contact tube that is slidingly connected with it; Described contact tube and conducting rod join domain are provided with banded contact; Described banded contact is fixedly connected on the contact tube, and described contact tube is provided with screw rod, and described conducting rod is provided with the hole of agreeing with mutually with screw rod.
Before the field test, in conducting rod indentation contact tube, and be screwed, break off, carry out power frequency withstand test after pouring SF6 gas with lightning arrester or voltage transformer.After the pass the test, skid off conducting rod, major loop is communicated with the element of downside, and transmission operation.
The beneficial effect of the utility model is: 1, the utlity model has simple and practical, reliability is high, be easy to characteristics such as field test.
2, the described conducting rod of the utility model stretches in contact tube, and lightning arrester, withstand voltage instrument transformer etc. can directly be installed, and has reduced process flow, has reduced workload, has improved operating efficiency.

Fig. 2 is the telescopic conducting rod structure of a 252kV combined electrical apparatus cutaway view.
Embodiment
The technical scheme that the utility model adopts is: the telescopic conducting rod of 252kV combined electrical apparatus; Comprise the contact tube 1 that is slidingly connected with it; It is characterized in that: described contact tube 1 is provided with banded contact 3 with conducting rod 2 join domains; Described banded contact 3 is fixedly connected on the contact tube 1, and described contact tube 1 is provided with screw rod 4, and described conducting rod 2 is provided with the hole 5 of agreeing with mutually with screw rod 4.
Can be between described contact tube 1 of the utility model and the conducting rod 2 through the loop current of 1600-3200A.
Before the field test, in conducting rod 2 indentation contact tubes 1, and be screwed, break off, carry out power frequency withstand test after pouring SF6 gas with lightning arrester or voltage transformer.After the pass the test, skid off conducting rod 2, major loop is communicated with the element of downside, and transmission operation.
The beneficial effect of the utility model is: 1, the utlity model has simple and practical, reliability is high, be easy to characteristics such as field test.
2, the described conducting rod of the utility model stretches in contact tube, and lightning arrester, withstand voltage instrument transformer etc. can directly be installed, and has reduced process flow, has reduced workload, has improved operating efficiency.
