Abstract
The invention relates to a portable insulation ladder used for disconnecting link and grounding brake observing windows of an HGIS (Hypid Gas Insulated Switchgear), which comprises an adjustable crawling ladder consisting of a side ladder and pedals, wherein an adjustable bracket is arranged at the upper end of the back surface of the side ladder, the lower part of the adjustable bracket is connected with the lower part of the side ladder through a pressing-preventing cable strut, the adjustable crawling ladder is a glass fiber reinforced plastics crawling ladder, the adjustable bracket is a glass fiber reinforced plastics bracket, and the pressing-preventing cable strut is a glass fiber reinforced plastics strut. The portable insulation ladder for the disconnecting link and the grounding brake observing windows of the HGIS solves the problem of inconvenient observation on the equipment operation condition from the upper observing window and the lower observing window of the HIGS, and has the advantages of small volume, light weight, good insulation, simple use and reliable observing structure, and is convenient to operate and carry.
Description
Technical field
The present invention relates to a kind of electric operating apparatus, relate in particular to a kind of HGIS of being used for disconnecting link, the portable insulating ladder of cutter observation port.
Background technology
1000kV extra-high voltage friendship system, ± 800kV extra-high voltage direct-current system electrical equipment, comprise equipment such as HGIS knife switch, lock and ground cutter, HGIS(Hybrid Gas Insulated Switchgear) is a kind of novel high-pressure switchgear between GIS and AIS, volume is big, and the characteristic that design is complicated, electric pressure is high has determined its complexity and danger.When carrying out the observation of electric fixtures physical location, since the observation port of HGIS directly over disconnecting link and the ground cutter air chamber and under, the observation port of top has 2.1 meters height apart from the level ground, the observation port of equipment air chamber below has 0.8 meter height apart from the level ground, and fortune inspection personnel are difficult to utilize endoscope to observe the physical location of equipment from observation port up and down.Usually adopt wire ladder or bamboo wooden ladder as the peep hole directly over the instrument observation of ascending a height at present, easily produce the generation that induced electricity or maloperation cause electric shock accidents, threaten operating personnel's safety; The mode that the peep hole of below then bends over to check by fortune inspection personnel, and there is the cable that can not by mistake bump in the observation port below, extremely inconvenient, and because the observed result that the observation time weak point obtains is unreliable.
Summary of the invention
Technical problem to be solved by this invention provide a kind of simple in structure be used for the HGIS disconnecting link, the portable insulating ladder of cutter observation port, solved from the problem of the upper and lower observation port facilities for observation of HGIS operation conditions inconvenience, Ti Ji Xiao ﹑ Chong Liang Qing ﹑ insulate, Shi is easy to carry with Jian Dan ﹑ operation, observation structure is reliable.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of be used for the HGIS disconnecting link, the portable insulating ladder of cutter observation port, comprise the adjustable cat ladder of forming by side ladder, pedal, upper end, the side ladder back side is equipped with adjustable support, the adjustable support bottom is connected by anti-voltage cable pillar with side ladder bottom, adjustable cat ladder is the glass fiber reinforced plastic cat ladder, and adjustable support is the glass fiber reinforced plastic support, and anti-voltage cable pillar is the glass fiber reinforced plastic pillar.
Side ladder bottom is provided with sheath.
Side ladder upper end is hinged with the glass fiber reinforced plastic platform.
Side ladder top is provided with anti-slide fastener.
Side ladder bottom is provided with protective earth.
Provided by the invention be used for the HGIS disconnecting link, the portable insulating ladder of cutter observation port, beneficial effect is as follows:
1, because adjustable cat ladder, adjustable support and anti-voltage cable pillar adopt glass fiber reinforced plastic to make, have the advantage of putting induced electricity, non-conductive, high strength, corrosion-resistant, good looking appearance and have good electrical properties, can prevent the electric shock accidents that induced electricity and anti-misoperation cause effectively, ensure operating personnel's safety; Adjustable cat ladder, support and anti-voltage cable pillar form a firm triangular structure, can be used for the observation that HGIS goes up observation port when placing vertically, can be used for the observation of observation port under the HGIS during traverse, simultaneously, because the existence of anti-voltage cable pillar, the unstable mistake of adjustable cat ladder is bumped the situation generation of cable in the time of can preventing traverse, solved from the problem of the upper and lower observation port facilities for observation of HGIS operation conditions inconvenience, Ti Ji Xiao ﹑ Chong Liang Qing ﹑ insulate, Shi is easy to carry with Jian Dan ﹑ operation, observation structure is reliable.
2, the sheath of side ladder bottom has effectively improved steadiness of the present invention and safety.
3, the glass fiber reinforced plastic platform can put down when the present invention places vertically, as depositing of operating personnel's pedal and instrument, has made things convenient for observation.
4, the design of anti-slide fastener makes that the glass fiber reinforced plastic platform was more tight with contacting of HGIS equipment when the present invention placed vertically, has guaranteed the reliability of observed result.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the present invention is applied to the schematic diagram that HGIS goes up observation port;
Fig. 3 is the schematic diagram that the present invention is applied to observation port under the HGIS.
The specific embodiment
As depicted in figs. 1 and 2, the present invention includes the adjustable cat ladder of forming by side ladder 1, pedal 2, upper end, side ladder 1 back side is equipped with adjustable support 3, adjustable support 3 bottoms are connected by anti-voltage cable pillar 6 with side ladder 1 bottom, adjustable cat ladder is the glass fiber reinforced plastic cat ladder, adjustable support 3 is the glass fiber reinforced plastic support, and anti-voltage cable pillar 6 is the glass fiber reinforced plastic pillar.
Side ladder 1 bottom is provided with sheath 7.
Side ladder 1 upper end is hinged with glass fiber reinforced plastic platform 8.
Side ladder 1 top is provided with anti-slide fastener 4.
Side ladder 1 bottom is provided with protective earth 5.
Adjustable cat ladder, adjustable support 3 and anti-voltage cable pillar 6 are main material and the glass fiber reinforced plastic shapes of pultrusion is processed into by glass fiber and epoxy resin.
It is as follows that the present invention is used for the use of the upper and lower observation port of HGIS:
As shown in Figure 2, when observation HGIS goes up observation port 10, the present invention is placed vertically in HGIS equipment 9 sides, anti-slide fastener 4 is connected with HGIS equipment 9 opposite sides, with protective earth 5 ground connection, fortune inspection personnel climb up side ladder 1 by pedal 2 can observe equipment operating condition directly over HGIS goes up observation port 10, guaranteed the reliability of observed result.
As shown in Figure 3, when observing under the HGIS observation port 11, with the below of traverse of the present invention in HGIS equipment 9, with protective earth 5 ground connection, fortune inspection personnel lie on the adjustable cat ladder operating condition of the equipment of can observing under the observation port under the HGIS 11, guaranteed the reliability of observed result, Cable Groove 12 can not bumped cable by mistake between anti-voltage cable pillar 6 and adjustable cat ladder at this moment.
