Abstract
The invention discloses a power isolating switch, belonging to the machinery technical field. The isolating switch mainly comprises an under frame, bearing supports, porcelain insulator pedestals, rain covers, conical bearings, wherein two ends of the under frame are respectively provided with the bearing supports; the conical bearing is arranged in each bearing support; the porcelain insulator pedestals are respectively locked on the bearing supports. The power isolating switch is characterized in that both the porcelain insulator pedestals and the rain covers are provided with vertical holes on the same position, the vertical holes are communicated with horizontal holes on the porcelain insulator pedestals; and the side wall of each bearing support is provided with a hole. The power isolating switch has the advantages of convenient maintenance and low maintenance cost.
Description
Technical field
The present invention relates to a kind of switch, specifically a kind of electric power isolating switch belongs to field of mechanical technique.
Background technology
The present 110kV high-tension circuit of China switches a kind of isolating switch of electrical equipment and the common usefulness of electrical isolation under immunization with gD DNA vaccine, its structure is that underframe is a channel-section steel, a bearing pedestal is respectively installed at the underframe two ends, bearing pedestal adopts the bell-jar semi-closed structure, the porcelain vase pedestal spiral-lock of upper end is on the bearing pedestal of bottom, prevent that by rain cover rainwater from entering in the bearing pedestal, between the cone bearing of rain cover and lower end (upper bearing (metal)) is semi-closed structure, rotating shaft and porcelain vase pedestal are welded as a whole, be rotatable parts, two taper roll bearings (lower bearing) are arranged in the bearing pedestal, guarantee that bearing pedestal rotates flexibly, thereby the porcelain vase that drives its upper end rotates.Because between the rain cover of porcelain vase pedestal rotor plate lower end and the cone bearing of lower end is semi-closed structure, though it can prevent entering of rainwater, but because the upper end of it and bearing pedestal is gapped, can not prevent the immersion of moisture, blowing and raining and malaria make isolating switch bearing pedestal inside the very easily oxidation of upper and lower bearing, get rusty, become rusty extremely to straight, influence the operate as normal of isolating switch.The isolating switch majority all is installed in outdoor operation, the maintenance cost height, and maintenance is also inconvenient, influences the reliability and stability of power supply unit.
Summary of the invention
Task of the present invention provides a kind of convenient for maintaining, the electric power isolating switch that expense is few.
For realizing above-mentioned task, technical solution of the present invention is:
A kind of electric power isolating switch, mainly constitute by underframe, bearing pedestal, porcelain vase pedestal, rain cover, cone bearing, the underframe two ends respectively are provided with a bearing pedestal, cone bearing is set in the bearing pedestal, porcelain vase pedestal spiral-lock is on bearing pedestal, its design feature communicates with the hole of horizontally set on the porcelain vase pedestal for vertical hole to be set on the same position of porcelain vase pedestal and rain cover, on the sidewall of bearing pedestal the hole is set.
Described a kind of electric power isolating switch is provided with in the vertical hole on the same position of porcelain vase pedestal and rain cover oviduct is set.
Described a kind of electric power isolating switch is provided with grease nipple respectively on the hole that is provided with on the hole of horizontally set on the porcelain vase pedestal and the sidewall at bearing pedestal.
The present invention has easy to maintenance, the advantage that maintenance cost is few.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of electric power isolating switch, mainly constitute by underframe 8, bearing pedestal 5, porcelain vase pedestal 1, rain cover 4, cone bearing 7, a bearing pedestal 5 is respectively installed at underframe 8 two ends, cone bearing 7 is installed in the bearing pedestal 5, porcelain vase pedestal 1 spiral-lock is on bearing pedestal 5, on the same position of porcelain vase pedestal 1 and rain cover 4, bore vertical hole, and installation oviduct 3, this hole communicates with the hole of laterally boring on porcelain vase pedestal 1, on the sidewall of bearing pedestal 5, hole, grease nipple 6 is installed on the hole of boring on hole of laterally boring on the porcelain vase pedestal 1 and the sidewall at bearing pedestal respectively.
In the time need cleaning to the bearing in the bearing pedestal, unload grease nipple, with gasoline or cleaning agent bearing is cleaned; In the time need carrying out grease up, squeeze to bearing from grease nipple with injection grease gun and to beat lubricating grease the bearing in the bearing pedestal.
Claims (3)
1, a kind of electric power isolating switch, comprise underframe, bearing pedestal, porcelain vase pedestal, rain cover, cone bearing, the underframe two ends respectively are provided with a bearing pedestal, cone bearing is set in the bearing pedestal, porcelain vase pedestal spiral-lock is on bearing pedestal, it is characterized in that: vertical hole is set on the same position of porcelain vase pedestal and rain cover, communicates, on the sidewall of bearing pedestal, the hole is set with the hole of horizontally set on the porcelain vase pedestal.
