Abstract
Provided is a novel distribution box for a dry-type transformer shell. The distribution box body controls a transformer through a line and is connected with the transformer. The distribution box body is of a cuboid structure, and is provided with a box door and a plurality of output ports. A terminal row of a secondary line is installed inside the distribution box body, an air switch which controls a power supply of the secondary line is further fixedly installed inside the distribution box body, and the terminal row and the air switch are both connected with lines and are leaded out from the output ports through the lines. The novel distribution box is without the need of opening of an electromagnetic safety door lock of the dry-type transformer shell, and is further without the need of cutting-off of a power supply of the transformer. The novel distribution box has the advantages of being high in safety performance, harmonious and beautiful in whole appearance, and convenient to implement.
Description
Technical field
The utility model belongs to the dry-type transformer fitting field, relates to a kind of novel distribution box that is used for dry-type transformer case.
Prior art
For the operation that guarantees that dry-type transformer is safe and reliable, most of products have all been installed protection systems such as the control automatically of temperature display system, blower fan, overtemperature alarm, tripping operation and Electromgnetic seat door lock.The secondary line of these protection systems is many and complicated.Air switch in the existing dry-type transformer control secondary line and connecting terminal block etc. all are directly installed on the panel of shell and the inwall of shell.
Most producers adopt air switch to be installed in the power supply of controlling secondary line on the dry-type transformer case outer panels, and are installed in the dry-type transformer case inwall with connecting terminal block and are used for connecting each secondary line.This kind way not only inconvenient secondary line maintenance but also influence the overall appearance of product.When running into the secondary line glitch; When needing the wiring of inspection connecting terminal block secondary control circuit or air switch, must open dry-type transformer case Electromgnetic seat door lock, before opening electromagnetic door lock; Safety for the maintainer; High pressure inlet wire or the transformer that must break off transformer be power-off protection voluntarily, whole transformer is all quit work, thereby influenced terminal use's normal electricity consumption because of the maintenance of some glitch.And the air switch of control secondary line power supply, be directly installed on the dry-type transformer case outer panels, not attractive in appearance also dangerous.
Summary of the invention
Above-mentionedly existingly, dry-type transformer protection system glitch to bring the transformer caused inconvenience that has a power failure in order to solve because of need overhauling its secondary line; Low and the inaesthetic problem of monnolithic case of security performance; The utility model provides a kind of novel distribution box that is used for dry-type transformer case; The Electromgnetic seat door lock that it need not open dry-type transformer case also need not break off power of transformer, it have security performance height, monnolithic case coordinate attractive in appearance, implement characteristics easily.
In order to achieve the above object, the utility model adopts following concrete technical scheme: a kind of novel distribution box that is used for dry-type transformer case, and its architectural feature is; The distribution casing is through circuit control and connect transformer; The distribution casing is cube structure, and the distribution casing is provided with chamber door, and the distribution casing is provided with a plurality of output ports; The set inside of distribution casing has the terminal board of secondary line; The air switch of control secondary line power supply also is fixedly installed on the distribution box house, and terminal board and air switch all are connected with circuit, and derive from output port through circuit.
In the time will overhauling secondary line, directly open little electronic box maintenance, need not open the Electromgnetic seat door lock of dry-type transformer case, need not break off power of transformer yet, directly open little electronic box, switch control power supply and safe ready ground maintenance circuit.Be installed in the air switch of secondary line power supply in the little electronic box, also improved the aesthetics of its fail safe and whole product.
The beneficial effect of the utility model is: the Electromgnetic seat door lock that it need not open dry-type transformer case, also need not break off power of transformer, it have security performance height, monnolithic case coordinate attractive in appearance, implement characteristics easily.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Fig. 1 is the utility model perspective view;
Fig. 2 is the internal structure sketch map after chamber door is opened in the utility model.
Embodiment
Like Fig. 1, shown in Figure 2, a kind of novel distribution box that is used for dry-type transformer case is characterized in that; Distribution casing 1 is through circuit control and connect transformer; Distribution casing 1 is cube structure, and distribution casing 1 is provided with chamber door 11, and distribution casing 1 is provided with a plurality of output port A; The set inside of distribution casing 1 has the terminal board B of secondary line; The air switch C of control secondary line power supply also is fixedly installed on distribution casing 1 inside, and terminal board B and air switch C all are connected with circuit, and derive from output port A through circuit.
Below the temperature controller of dry-type transformer case, open a 185mmX235mm square hole.The little case of distribution of long 180mm, high 230mm, dark 100mm is installed in the square hole, and a DZ47-63 air switch and 12 connecting terminal blocks are joined in little case inside.Insert little electronic box to the secondary line and the used power supply of dry-type power transformer protection systems such as the control automatically of temperature display system, blower fan, overtemperature alarm, tripping operation and Electromgnetic seat door lock by winding diagram.In the time will overhauling secondary line, directly open little electronic box and get final product with instruments such as universal instrument maintenance secondary line.
