Abstract
The utility model discloses a protecting jacket for a disconnecting link transmission main shaft. The protecting jacket comprises a left box body and a right box body, wherein the left box body is embedded into the right box body; the left box body and the right box body are hinged together; and the upper ends of the left box body and the right box body are provided with semicircular through holes of equal diameters. The protecting jacket has a simple structure and light weight, is convenience for installing, and is accepted widely by overhauling, running and operating personnel; the protecting jacket is made of a stainless steel piece, so that the probability of rusting on a three-phase support point shaft of a main disconnecting link transmission main shaft effectively lowered; and an isolating switch is convenient and flexible for operating, so that switch on/off is appropriate, running of equipment is more stable, and good safe and economic benefits are achieved.
Description
Technical field
The utility model belongs to the power equipment protector, relates in particular to disconnecting link transmission main shaft protective sleeve.
Background technology
Sanmenxia Gorge service area of electric company is located in the Henan Xishan District, and undertaking is that three counties, area, the Sanmenxia Gorge, two liang district socio-economic development provide safety, reliable, continuous unobstructed supply of electric power task.The 220kV high voltage isolator unit type of having jurisdiction over mainly contains GW4, GW6, GW16, GW17 type at present; Along with the increase of the operation time limit, deciliter not in place, the equipment corrosion of isolating switch, connecting rod cracking, mechanism's locking are stuck etc., and phenomenon increases day by day; Wherein many problems are because there are inadequate natural endowment in design, material and the secondary circuit of isolating switch itself, thereby equipment these accident defects in running come out gradually.Under 220kV equipment power failure situation of difficult, phenomenons such as the fault of isolated switchgear takes place frequently, ultra time between overhauls(TBO) have a strong impact on the safe operation of system especially.
GW16 (17)-220 type isolating switch is that table mountain switchgear plant produces, and belongs to early production.Through the long-time running in nearly ten years, the assembling of the main switch cutter of isolating switch, ground connection plug-in strip, rotation insulator and support insulator, the assembling of combination base, drive system and electric operating mechanism all went wrong the wherein main machine driven system part that concentrates in various degree; In the long-time running process; Through exposing to the sun and rain, snow, water-soaked are got rusty it, cause frictional force to increase; Stuck phenomenon appears in severe patient; And causing divide-shut brake same period, not in place not, operating mechanism falls high easily, repeatedly causes equipment to delay to send.
The utility model content
The utility model problem to be solved provides a kind of disconnecting link transmission main shaft protective sleeve, thereby minimizing causes frictional force because of getting rusty, and reduces accident rate.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of disconnecting link transmission main shaft protective sleeve; Comprise left box body and right box body; Left side box body is nested in the right box body, and is hinged between left box body and the right box body, and left box body and right box body upper end are provided with isodiametric semi-circular through hole.
The edge of described right box body one side is hinged on the side of left box body through hinge.
The utility model is simple in structure, in light weight, easy for installation, receives maintenance, operation personnel's generally approval; Be made by stainless steel part, effectively reduced the probability that main switch cutter transmission main shaft three-phase strong point axle gets rusty, isolator operation is light, flexible, and opening and closing in place makes equipment operation more stable, has obtained good safety, economic benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, a kind of disconnecting link transmission main shaft protective sleeve comprises left box body 1 and right box body 2; Left side box body 1 is slightly smaller than right box body 2, and left box body 1 marginal portion is nested in the right box body 2, and the edge of right box body one side is hinged on the side of left box body through hinge; Left side box body 1 is provided with isodiametric semi-circular through hole 3,4 with right box body 2 upper ends, closes up the back and forms circular hole or flat round hole, and the lower end of left and right box body does not all have baffle plate.
Claims (2)
1. disconnecting link transmission main shaft protective sleeve, it is characterized in that: comprise left box body and right box body, left box body is nested in the right box body, and is hinged between left box body and the right box body, and left box body and right box body upper end are provided with isodiametric semi-circular through hole.
2. disconnecting link transmission main shaft protective sleeve according to claim 1 is characterized in that: the edge of described right box body one side is hinged on the side of left box body through hinge.
