Abstract
The utility model relates to a general dry transformer for a mine, composed of a core body composed of a transformer iron core and a winding, a high and low pressure wire connection chamber, a high and low pressure leading wire sleeve pipe (the interior is provided with the leading wire), a casing, and a bottom cart. The material of the iron core is a cold rolling grain-oriented silicon steel sheet and has no punching hole; the winding uses the aromatic polyamide of insulation material; the high and low pressure wire connection chamber and the high and low pressure sleeve pipe respectively use a standard part; the casing is pressed into a corrugated plate by using a steel plate of 4m/mA3, and the lower part is provided with the bottom cart. The product has small size, less loss, low temperature rise, convenient moving and safety, and has no pollution.
Description
Mining GENERAL TYPE dry-type transformer is the underground power supply used equipment of using in a kind of colliery.The core body that its main body is made up of transformer core and winding, high-low pressure wire connection cavity, high-low pressure lead-in wire sleeve pipe (interior dress lead-in wire), shell, end car are formed, and this is the ideal equipment that is best suited for the coal mine operation power supply.
The transformer that uses under the existing coal mine mostly is KS7 series oil-filled transformer and explosion-proof dry-type transformer.The problem that oil-filled transformer exists is that volume is big, is difficult for carrying, and shell is a heat radiating flat tube, easily breaks in carrying and causes leakage of oil, contaminated environment, fire hazardous; Explosion-proof dry-type transformer also exists volume big, is difficult for carrying, the cost height, and riding position only limits to tunnel or face, so above-mentioned two kinds of transformers all are not the ideal transformers of coal mine operation.
The drawback that the objective of the invention is to exist at above-mentioned two kinds of transformers, newly design that a kind of volume is little, temperature rise is low, loss is little, pollution-free, conveniently moving and safe and reliable, every price is than the new type mining GENERAL TYPE dry-type transformer that is best suited for the underground power supply used usefulness in colliery of explosion-proof dry-type transformer cheap 40%.
What invention main points of the present utility model were that this transformer core selects for use is a kind of quality material-cold rolling grain oriented silicon steel sheet, no punching, and the surface is coated with the are-tight lacquer of insulation; Winding adopts special insulating material aromatic polyamides, garden core structure; Shell adopts 4m/mA
3Steel plate is pressed into corrugated board.
Outstanding advantage of the present invention is that the serviceability temperature of this electric equipment can keep stable over a long time electrical property and mechanical performance under 200 ℃ situation, has firm wear-resisting, tear-resistant, corrosion-resistant, humidity, characteristics such as nontoxic.
Description of drawings
Fig. 1 and Fig. 2 are structural representation of the present utility model, and 1 among Fig. 1 is iron core, and 2 is winding, and 3 is the core body that iron core and winding are formed, and 4,5 is the high-low pressure wire connection cavity, and 6,7 are high-low pressure lead-in wire sleeve pipe (interior dress lead-in wire), and 8 among Fig. 2 is shell, and 9 is end car.

(1)The surface is coated with the are-tight lacquer of insulation, can be anticorrosion, antirust, solar heat protection, protection against the tide, and iron core
(1)The thermal relay monitor temperature is housed; Winding
(2)The insulating material aromatic polyamides, the garden core structure, can improve voltage distributes, improve the serviceability temperature of shock-resistant ability and steady control electric equipment, under 220 ℃ of high temperature, keep not changing its electrical property and mechanical performance over a long time, have firm wear-resisting, tear-resistant, corrosion-resistant, humidity, nontoxic characteristics; The high-low pressure wire connection cavity
(4,5)Employing standard connection is by high-low pressure lead-in wire sleeve pipe in the chamber
(6,7)Interior lead-in wire is connected with the down-hole high pressure switch, and its high pressure is that Y connects, and low pressure is the Yd conversion, high-low pressure lead-in wire sleeve pipe
(6,7)Also adopt normal sleeve, interchangeability is good; Shell
(8)Adopt 4m/mA
3Steel plate is pressed into corrugated plating, has both increased area of dissipation, has improved intensity, shell again
(8)End car is equipped with in the bottom
(9), can travel conveniently moving at underground orbit.
This GENERAL TYPE dry-type transformer is the most advanced at present ideal equipment that is suitable for the underground power supply used usefulness in colliery.
Claims (2)
