Abstract
The utility model discloses an isolating switch protective sleeve which is characterized in that the isolating switch protective sleeve includes a cover housing and threading pipes; the cover housing is a rectangular box which is open downward, and the two ends of the box are provided with the threading tubes which are communicated with the inside of the box; the threading tubes are arranged on the same central line; the box is composed of two symmetrical half boxes along the central line of the threading tubes. The top of the back of the cover housing and the two sides of the cover housing are provided with butt buckles. The isolating switch protective sleeve also includes an isolating switch, and the cover housing completely covers the insolating switch and leads on the two ends of the isolating switch from the top of the isolating switch through butt connection. The isolating switch protective sleeve can guarantee the operation safety of an operator, reduce the device faults, and guarantee the safe running of a power supply device.
Description
Technical field
The utility model relates to a kind of isolating switch protective sleeve, is applicable to the protection of isolating switch.
Background technology
The isolating switch reliability requirement is high, is the critical facility in the power transmission and transformation line, especially high voltage isolator, to use maximum a kind of switch electric installations, although although its principles and structure is simple, to electric substation, the design of power plant and safe operation impact are very large.Isolating switch mainly is used for the part that needs in the high voltage distribution installation to have a power failure is reliably isolated, to guarantee the safety of service work.Isolating switch does not have arc-control device, can not cut off load current or short circuit current, can only be lower minute of uncharge situation, close circuit.Isolating switch is used for each step voltage, disconnects as changing circuit connection or equipment and power supply, and it can only again operation after with other equipment circuit being disconnected without the cutout ability.Outdoor high voltage isolator is in wind and rain, ice and snow, filth, and the adverse circumstances such as condensation, frost, contact portion is overheated so its most common failure has, contact resistance increases, can cause electric arc in the drawing process, burn contact etc.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, practical and convenient isolating switch protective sleeve.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of isolating switch protective sleeve is characterized in that: comprise case and penetration pipe; Described case is downward opening cuboid box, and described box two ends are respectively equipped with the penetration pipe that is communicated with cassette interior, and described penetration pipe is positioned on the same center line, forms along the half box docking by two symmetries of the center line box of penetration pipe.
The further improvement that the utility model is done is: top, back and both sides at described case are provided with the docking buckle.Also comprise isolating switch, described case all covers by the wire of docking with isolating switch and two ends thereof from the isolating switch top.
The beneficial effect that adopts technique scheme to produce is: the protective sleeve of insulated plastic glue material all covers isolating switch; stopped erosion by wind and rain; alleviated the pollution of atmosphere to isolating switch; can avoid phase fault if any Bird's Nest; can wear out by protective separation switch parts; can avoid phase fault if any electric arc, make the operation of the isolating switch of leaving behind become more convenient.Guarantee operating personnel's handling safety, reduced equipment fault, guaranteed the power supply facilities safe operation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the front view of a kind of isolating switch protective sleeve of the utility model;
Fig. 2 is the upward view of Fig. 1.
As shown in the figure: 1 wire, 2 penetration pipes, 3 docking buckles, 4 cases, 5 isolating switches.
Embodiment
Contrast Fig. 1 uses step to be described further to operation of the present utility model: a kind of isolating switch protective sleeve comprises case 4 and penetration pipe 2; Described case 4 is downward opening cuboid box, and described box two ends are respectively equipped with the penetration pipe 2 that is communicated with cassette interior, and described penetration pipe 2 is positioned on the same center line, forms along the half box docking by two symmetries of the center line box of penetration pipe 2.Top, back and both sides at described case 4 are provided with docking buckle 3.Also comprise isolating switch 5, described case 4 all covers from isolating switch 5 tops by the wire of docking with isolating switch 5 and two ends thereof.
Isolating switch sheath of the present utility model adopts the injection mo(u)lding of insulated plastic glue material, and two and half boxes are connected into a Global Macros cover by 3 pairs of buckles of docking.Before installing, carry out following preparation: 1, the dust on cleaning porcelain piece surface checks whether the porcelain piece surface falls glaze, breakage, and flawless and flashover vestige are arranged, whether the iron of insulator, porcelain binding site is firm.If badly broken should be changed; 2, clean greasy dirt on blade, contact or the fingertip with gasoline, check whether contact surface cleans, and has no mechanical damage, the phenomenons such as oxidation and overheated vestige and distortion, distortion; 3, check whether the annex on contact or the blade is complete, have or not damage; 4, check whether the lead-in wire of connection isolating switch and bus, circuit breaker is firm, have or not superheating phenomenon; 5, check that the parts that are flexible coupling have or not the phenomenons such as the thigh of losing, break; 6, check and cleaning operation mechanism and running part, and add an amount of lubricant grease; 7, check whether the distance of running part and live part meets the requirements; Whether whether locator and brake apparatus be firm, move correct; 8, check whether the base of isolating switch is good, and whether ground connection is reliable.After finishing above-mentioned work, in isolating switch 5 uncharged situations, protective sleeve is all covered from isolating switch 5 tops by the wire of docking with isolating switch 5 and two ends thereof, and by tight docking buckle 3.
