Description

Water proof type transformer and its assembly technology
Technical field
The present invention relates to a kind of transformer, especially relate to a kind of have the new transformer having a stronger water-proof function and Its assembly technology.
Background technology
At present, energy-conservation, reduction of discharging are advocated by State-level, during therefore transformer uses the application structure of open-close type due to The advantages of easy for installation, repeatable dismounting assembling, maintenance cost are cheap and obtained the wide use sent out;But, due to transformer Work out of doors, can it be corroded rain, the transformer of especially this kind of retractable structure, if iron core end face receives rain The invasion and attack of water, precision can drastically decline, thus greatly reducing the precision of transformer.
Nowadays, outdoor mutual inductor on the market, in order to reach waterproof effect, has simply carried out end face processing, for example, plus one Individual collision mat, such as Chinese patent 201410226586.3 disclosed " a kind of transformer with water proof type shell ", its not from In overall structure, water resistance is made with design, be therefore unable to reach good waterproof effect.
Content of the invention
Water proof type transformer and its assembling of a kind of good sealing effect, it is an object of the invention to overcoming above-mentioned deficiency, are provided Technique.
The object of the present invention is achieved like this:
A kind of water proof type transformer it is characterised in that: described water proof type transformer comprise cored, skeleton, collision mat, line bag and Shell,
Described iron core is the circulus being involuted by left semi-ring and right semi-ring,
Described skeleton is the circulus being involuted by left side and right-hand part, and left semi-ring and right semi-ring are embedded in a left side respectively In half portion and right-hand part, described left side and right-hand part are provided with installation baffle plate on the end face of pairing, and collision mat is set in On this installation baffle plate;Wired bag is wound around on described left side or right-hand part;
Described shell includes left shell half body and right half-shell body, described left shell half body and right half-shell body is respectively arranged with and lays structure Become the left side of skeleton and the caulking groove of the c shape structure of right-hand part, and vertical on the cell wall of the caulking groove of left shell half body and right half-shell body It is provided with shell close-fitting groove, the both sides of collision mat are embedded in this shell close-fitting groove, are placed with left side and the right-hand part of skeleton Caulking groove in be perfused with epoxy resin.
A kind of present invention water proof type transformer, the shell wall of described left shell half body and right half-shell body is mounted on connect Wear between block, and the contiguous block of the contiguous block of left shell half body and right half-shell body and be connected to fastening bolt, described left shell half body or right half Water joint is provided with housing.
A kind of present invention water proof type transformer, described left side and right-hand part are formed by upper and lower covers pressing, a left side for iron core Semi-ring is pressed together between the upper and lower covers of left side, and the right semi-ring of iron core is pressed together between the upper and lower covers of right-hand part.
A kind of present invention water proof type transformer, is provided with spring leaf in described left side, this spring card be placed in iron core and Between skeleton;Wired bag is wound around on described right-hand part.
A kind of assembly technology of water proof type transformer, described technique includes following steps:
Step one: the left semi-ring and right semi-ring that constitute iron core are respectively mounted the entrance left side of skeleton and the mounting groove of right-hand part In, and it is provided with spring leaf between the cell wall of the ring wall of left semi-ring and left side mounting groove;
Step 2: collision mat loaded onto by set on the installation baffle plate of the left side of skeleton and right-hand part;
Step 3, right-hand part is wound around and reaches the standard grade bag;
Step 4, left side and right-hand part are individually positioned in left shell half body and the caulking groove of right half-shell body, collision mat is inserted in In shell close-fitting groove on caulking groove inwall, the external output current signal of the water joint through being installed on right half-shell body for the line bag;
It is perfused with ring in step 5, the left side laying composition skeleton and the left shell half body of right-hand part and the caulking groove of right half-shell body Oxygen tree fat;
After step 6, band epoxy resin cure, upper cover body is pressed on left shell half body and right half-shell body;
Step 7, using the contiguous block being installed on left shell half body and the external shell wall of right half-shell, by the bolt through contiguous block Left shell half body and right half-shell body are pressed together, in bonding processes, waterproof sealing is realized by collision mat, pass through bullet simultaneously The elastic force that reed provides enables to constitute the left semi-ring of iron core and right semi-ring firmly presses together.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts the pre-buried design of large scale collision mat, and collision mat is previously charged into skeleton, with skeleton again together be inserted in shell (close-fitting being realized by shell close-fitting groove, reach sealing effectiveness), thus ensure that the waterproof of two aspects:
First, end face is entirely to touch collision mat by collision mat, and after tensioning screw, extruding collision mat deformation (adopting rubber) stops completely The entrance of external water source;
2nd, collision mat is pressed into shell it is ensured that there being certain pressure using the formula that is inserted into along groove, thus the water source of outside cannot be introduced into outward Inside shell;
By monoblock type waterproofing design, this patent thoroughly solves the protection question of transformer outwork, can reach country's mark The degree of protection ip67 of quasi- gb4208.
Meanwhile, transformer of the present invention has the advantages that precision is good, and this is due on being related to, constituting the (right of skeleton Semi-ring) coiling, another side (left semi-ring) designs a spring leaf in skeleton, so ensure that iron core connects in left and right semi-ring Tactile end contact have sufficiently elasticity it is ensured that it can fit tightly together, thus ensure that the precision of transformer.
