Abstract
A box-type transformer comprises high and low pressure control switches, a transformer, and a casing. The high and low pressure control switches are respectively connected with the primary one-level circuitry of the transformer in series and are arranged in the casing along with the transformer. The transformer is a dry-type transformer and engaged with a radiator fan, and an over-current over-load protector is equipped in a power circuitry. Due to the adoption of the air-cooled dry-type transformer, the size is reduced and the daily maintenance for preventing insulation damage is avoided, and the safety of the over-current over-load protector is increased.
Description
Technical field
The utility model relates to a kind of power distribution equipment, is specially a kind of box type transformer.
Background technology
Existing box type transformer is switch combination unit, adopts oil-filled transformer, its weak point is: its type of cooling adopts transformer oil to cool off, transformer oil is in operation and contacts with air, and Quality of Transformer Oil can degenerate gradually, and electric insulation intensity reduces gradually.So in use must often take maintenance measure to transformer oil.And protective device is not established in inside, and the casing volume is bigger, not easy to assemble and long-distance transport.
Summary of the invention
The purpose of this utility model just provides a kind of be made up of air-cooled transformer of dry type and protective device, little easy-to-dismount box type transformer of volume.
The technical solution of the utility model is: comprise dual pressure control switch; transformer, casing; dual pressure control switch is serially connected with respectively in the primary and secondary circuit of transformer; they and transformer all place in the casing; it is characterized in that: described transformer is a dry-type transformer; the in addition cooling fan supporting with it also has the over-current and-load protector in power circuit.
Described blower fan is positioned at the casing of the below of transformer, is connected in series temperature controller in its electric power loop, and the temperature sensor of this controller places on the transformer body.
Described over-current and-load protector is an automatic air-break switch.Be serially connected with before the control switch of low-voltage circuit.
Voltmeter, ammeter and single-phase switch also are set in the low-voltage circuit, in high-tension line, also have fuse.
At described casing is dismantled and assembled structure, is covered with the louvered louvre in its both sides; In its front the door of splitting is arranged, ammeter and voltmeter are installed on door.
The utility model has the advantages that: owing to adopt air-cooled dry-type transformer, both reduced volume and also avoided the regular maintenance that degenerates and carry out for preventing to insulate; Its over-current and-load protector has increased fail safe.
The utility model is described in further detail below in conjunction with drawings and Examples.
