In force, transformer breathing equipment is also referred to as transformer breather or transformer silica gel tank, it is therefore an objective to for absorption
Enter the moisture in conservator poly-bag, membrane, removing and the dry change with temperature of oil in transformer in air and enter transformer oil storage
Debris and moisture in the air of cabinet, in case transformer makes moist, so as to ensure the dielectric strength of transformer oil.Work as transformer temperature
When reduction, oil level decline, transformer sucks gas by respirator, and gas first passes through oil sealing and carried out the dust in gas
Filter, is then passed through silica gel room, is adsorbed the moisture in gas by silica gel so that done into the cleaning gas in capsule
It is dry.In order to keep the normal operation of transformer, it is necessary to periodically be replaced to the silica gel in respirator.
When being replaced in view of power equipment maintaining personnel to silica gel, in order to ensure the safety of power equipment maintaining personnel, it is necessary to protect
Demonstrate,prove the safe distance between transformer breathing equipment and electrical body.Provided according to safety code, peace when 35kV equipment does not have a power failure
Full distance is 1m, and the selection for extending length of tube can be different from electrical body distance true according to the transformer breather of different model
It is fixed, as long as meeting safe distance.
Specifically, as shown in Figure 1, being respectively welded nut at the both ends of extension tube, the nut 1 of one end is screwed in transformer
At gasket on exposed screw rod 11, it is connected with the nut 2 of the other end and extends bolt 21；
The vertical nut 22 perpendicular to side wall, vertical nut 22 and breathing are welded with the side wall for extending 21 head of bolt
One end of threaded rod 23 in device is connected, the other end and the threaded hole phase on breathing equipment top cylindrical body 3 of threaded rod 23
Even, it is equipped with clamp nut 231 at 23 both ends of threaded rod.
According to the specifications and models of transformer insulated pad fastening bolt, the extension tube for being adapted specification is selected, respectively at both ends
Weld the nut (such as selecting the nut of internal diameter 12mm) of equivalent specifications.One end nut is fixed on exposed spiral shell at transformer sealing gasket
On bar 12, the other end is then connected by nut 2 with the extension bolt 21 of an equal model, and one is welded again extending 21 head of bolt
A vertical nut 22 perpendicular to head, effect are the fixed threaded rods being connected with breathing equipment, and can be real according to breathing equipment
The difference of border position does 360 ° of rotations.
23 one end of threaded rod nut 22 vertical with extension tube is connected, on the other end and thread bush top cylindrical body 3
Threaded hole is connected, and is fastened respectively with clamp nut 231.The thread cap of breathing equipment is fixed, and replaces hygroscopic agent, that is, silicon
During glue, breathing equipment lower end need to only be unscrewed, it is convenient and efficient.
Optionally, it is equipped with connector between screw rod exposed at the extension tube and transformer sealing gasket.Connector bag
Cylinder is included, mounting hole is equipped with the end face centre position of cylinder, the hole post of default quantity is equipped with centered on mounting hole,
The madial wall of hole post is equipped with the screw thread being connected with extension tube one end screw rod
In force, it is equipped with connector 12 between screw rod 11 exposed at the extension tube and transformer sealing gasket.
In force, most of connector of transformer breathing equipment is plastic material, originally proposes that selection can add again
The aluminum products finished product of work transformation, light weight, corrosion resistance, fastness are all preferable, but aluminum products moulding process is more complicated, commission
Foundry cost is higher.By determining selection easy purchase, easy processing after investigation, price is low, corrosion resistance is preferable, and mechanical strength
Height, plasticity is strong, the low nylon plastic(s) rod of cost.
Extension tube upper end and transformer flange connector 12, the structure of the connector 12 are specific as shown in Fig. 2, by plastics
Rod is processed into an a diameter of 11.5cm, and the cylinder of high 3cm, is punched, bore dia 1cm, with circular hole in its center position
Centered on be processed into the described screwed hole post 121 of wall thickness 1cm, high 1.5cm, as the connection with corrugated stainless steel tubing.According on flange
Hole position, punched respectively on the round sheet connector left, as with the fastening of the bolt of flange.
Optionally, the gasket is silicagel pad.
In force, silicagel pad is a kind of product that the market demand is more in silica gel product.There is certain tension force, flexible
Property, excellent insulating properties, pressure-resistant, high temperature resistant, low temperature resistant, chemical property stabilization, Environmental Safety, free from extraneous odour, food grade silicone pad
It is a kind of green product of high activity with nonpoisonous and tasteless, not soluble in water and any solvent.
Optionally, the extension length of tube is 1.5m.
In force, a corrugated stainless steel tubing is installed below connector additional, length (provides, 35kV for 1.5m according to safety
Safe distance is 1.0m when voltage class equipment does not have a power failure, and Bellows Length can need appropriateness increase and decrease according to scene).In this way,
When replacing respirator hygroscopic agent, since safe distance is enough, livewire work can be switched to by power failure work.The stainless steel wave of selection
Line pipe, is specific to the more demanding occasion design of water, oil, gas body, and the product through pass the test.
Optionally, the extension tube is corrugated stainless steel tubing.
In force, corrugated stainless steel tubing is installed in liquid conveying system as a kind of flexible pressure-resistant pipe fitting, to mend
Pipeline or machine, the mutual displacement of equipment connecting pin are repaid, vibrational energy is absorbed, vibration damping, noise reduction etc. can be played the role of, is had soft
The multinomial features such as property good, light weight, corrosion-resistant, antifatigue, high-low temperature resistant.
Wavy metal pipe stiffness makes metal bellows or other flexible members produce the required load value of unit displacement and claim
It is general to be represented with " K " for the rigidity of element.If the elastic characteristic of element is nonlinear, rigidity is no longer constant, but
Change with the increase of load.It is firm that the rigidity that the design of nominal rigidity flexible member provides when calculating is known as nominal (or specified)
Its actual measurement rigidity with element of degree has error, the particularly flexible member with nonlinear elasticity characteristic.What nominal rigidity represented
It is which point rigidity on curve, then thinks over.In general, nominal rigidity had better not be calculated directly using design
Value, but correction value of the product prototype after test should be used.Rigidity allows when rigidity franchise tests a collection of flexible member
Dispersion range.To being not quite similar with batch flexible member, the rigidity of each element of flange-connection stainless steel metal flexible pipe, there is one to disperse
Scope.In order to ensure the performance of element, must just there is a restriction to rigidity dispersion range.To elastic sensing element, its
Rigidity tolerance requirements are limited within +/- the 5% of nominal value；The ripple tubing flexible member of common engineering, rigidity franchise can
It is limited within +/- 50%.
