Abstract
An SF6 gas bottle heating jacket comprises two semicircular heating plates, a plurality of lock catches and an electrical plug; the two semicircular heating plates are arranged in an inner periphery facing manner, side surface edges at one ends of the two semicircular heating plates are hinged together, heating wires are arranged in the heating plates, and side surface edges at the other ends of the two semicircular heating plates are provided with the plurality of lock catches; and the electrical plug is arranged on the external surface of anyone of the heating plates and are electrically connected with the heating wires in the heating plates. The SF6 gas bottle heating jacket can substantially reduce the residual gas quantity in an SF6 gas bottle, so waste avoiding and production cost reduction are realized. Additionally, the SF6 gas bottle heating jacket has the advantages of simple structure, simple use method, low cost, obvious effect and the like.
Description
Technical field
The invention belongs to electric power apparatus examination device technique field, particularly relate to a kind of SF6 gas cylinder heating resistance collar.
Background technique
At present, domestic Operation of Electric Systems a large amount of SF6 closed composition electrical equipments.But, along with the use of these closed composition electrical equipments, the equipment Air Leakage Defect increases frequently, at this moment just need to be repaired the fault place, after reparation, also need its inside is supplemented to SF6 gas.Inflation adopts the SF6 gas cylinder to carry out usually, the SF6 gas that belongs to inert gas and be compressed into liquid condition is housed in the SF6 gas cylinder, pressure is 1MPa, during general inflation, utilize gas pressure difference in the interior pressure of gas of gas cylinder own and equipment to be filled with, but in gas cylinder air release to equipment in gas pressure quite after, the bottle in remaining gas can't inject.The every 50 kilograms of prices of SF6 gas are 10,000 yuan of left and right at present, as the gas of residue 20% in gas cylinder, will cause the gas waste of about 2000 yuan, thereby cause cost of production to raise, and this situation is not that clearly weather is colder in summer, wastes more serious.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of SF6 gas cylinder heating resistance collar that can cut the waste.
In order to achieve the above object, SF6 gas cylinder heating resistance collar provided by the invention comprises two semicircle heating plates, a plurality of snap close and electric connector; Wherein two semicircle heating plate modes relative with inner peripheral surface arrange, and an end side surface edge is hinged, and heating wire is equipped with in inside, and a plurality of snap closes are installed on the other end lateral edge; Electric connector is arranged on the outer surface of arbitrary heating plate, and is electrically connected to the heating wire in heating plate.
The diameter of described semicircle heating plate equals the external diameter of SF6 gas cylinder.
SF6 gas cylinder heating resistance collar provided by the invention can reduce the quantity of residual gas in the SF6 gas cylinder in a large number, therefore can avoid waste, and reduces production costs.In addition, this device also has simple in structure, using method, cost is low and the advantage such as successful.
The accompanying drawing explanation
Fig. 1 is SF6 gas cylinder heating resistance collar structural representation provided by the invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, SF6 gas cylinder heating resistance collar provided by the invention is elaborated.
As shown in Figure 1, SF6 gas cylinder heating resistance collar provided by the invention comprises two semicircle heating plates 1, a plurality of snap close 2 and not shown electric connectors; Wherein two semicircle heating plate 1 modes relative with inner peripheral surface arrange, and an end side surface edge is hinged, and heating wire is equipped with in inside, and a plurality of snap closes 2 are installed on the other end lateral edge; Electric connector is arranged on the outer surface of arbitrary heating plate 1, and is electrically connected to the heating wire in heating plate 1.
The diameter of described semicircle heating plate 1 equals the external diameter of SF6 gas cylinder.
Now SF6 gas cylinder heating resistance collar using method provided by the invention is described below: the air release in the SF6 gas cylinder is to when being inflated in equipment gas pressure and can't continuing to inject after quite, at first the opening end of two semicircle heating plates 1 is opened and be trapped among on the outer circumferential face of SF6 gas cylinder by operator, then by snap close 2 lockings, utilize afterwards electric connector to switch on power, the heat that utilizes the interior heating wire of heating plate 1 to produce is heated the SF6 gas that has been compressed into liquid condition in gas cylinder, be transformed into gaseous state after making it absorb heat, thereby rising gas cylinder outlet pressure, at this moment remaining gas in gas cylinder can be used.
Claims (2)
1. a SF6 gas cylinder heating resistance collar, it is characterized in that: it comprises two semicircle heating plates (1), a plurality of snap close (2) and electric connector; Wherein with inner peripheral surface, relative mode arranges two semicircle heating plates (1), and an end side surface edge is hinged, and heating wire is equipped with in inside, and a plurality of snap closes (2) are installed on the other end lateral edge; Electric connector is arranged on the outer surface of arbitrary heating plate (1), and is electrically connected to the heating wire in heating plate (1).
2. SF6 gas cylinder heating resistance collar according to claim 1, it is characterized in that: the diameter of described semicircle heating plate (1) equals the external diameter of SF6 gas cylinder.
