Abstract

The utility model discloses a split type oil transformer group, it includes box, case lid, coalesced copper pipe, radiating fin, backup pad, transformer, electric elements, and the box is square trough - shaped structure, is equipped with banding draw -in groove in bottom half both sides corner, and the lock that the backup pad both sides can be corresponding is in the draw -in groove of bottom half, and transformer and electric elements set up on the upper portion of backup pad, and radiating fin is connected to the lower part of case lid through the connecting plate, and it has the coalesced copper pipe to alternate at the radiating fin mesocycle. It has uses nimble convenient, whole quality low grade advantage, under the prerequisite that does not influence the disposition of equipment effect, has increased the flexibility in the in -service use. The split type structure of equipment adoption, the transformer subassembly can take off alone, install alone, has lightened the whole quality of equipment, and the installation is also more convenient than equipment before with the transport, but according to actual need selects the number of installation transformer subassembly, and is nimble convenient.

Description

Split type oil-cooled transformer group

Technical field

The utility model belongs to industrial microwave apparatus power supply module, specifically a kind of structure simple, use flexibly split type oil-cooled transformer group easily.

Background technology

Above Current Domestic technical grade micro-wave drying equipment, topmost components and parts are magnetron and high-tension transformer, wherein transformer can produce heat when work because electric current flows through in the windings, this part energy is also run off as loss, caloric value is larger, loss is larger, the part of so doing work is also less, when temperature rises to the epidermis insulating lacquer layer being enough to destroy enamelled wire time, winding burns out, transformer will be destroyed, therefore, industrial microwave apparatus is a crucial problem for the heat radiation of transformer in producing, and present situation domestic is at present the factor due to cost and place and manufacture difficulty or ease, everybody gets used to carrying out air-cooled to transformer, air-cooled advantage is that installation distribution is easy, blower fan is used to dry, cost is also low, shortcoming is that radiating effect is poor, the heat of a blowout can take to again above other transformers, wind back and forth can cause the high-temperature area of a local, heat can not be taken away, make the operational environment extreme difference of transformer.Another good radiating mode is oil cooling, exactly transformer is immersed in oil the inside, the every aspect of transformer is all contacted with heat eliminating medium, produces heat trnasfer always, circulated timely heat is taken away by condenser.

Applicant files an application March 5 in 2014 and has been the patent disclosure of CN203721429U a kind of oil cooling mode that adopts carries out the combined transformer power supply cooled in the Authorization Notice No. of authorizing on July 16th, 2014, in use there is the heavier problem of total quality in this product, the actual underaction that uses is convenient, and therefore applicant makes further improvement to equipment on this basis.

Summary of the invention

This use is novel is split type oil-cooled transformer group, and it has the advantages such as flexible and convenient to use, total quality is low, under the prerequisite not affecting equipment use effect, adds the flexibility in actual use.

The utility model realizes above-mentioned purpose by the following technical solutions:

Split type oil-cooled transformer group, it comprises casing, case lid, oxygen-free copper pipe, radiating fin, supporting bracket, transformer, electric component.

Described casing is square channel-shaped structure, is provided with the draw-in groove of strip in bottom half both sides corner; Described supporting bracket both sides can be fastened in the draw-in groove of bottom half accordingly, and described transformer and electric component are arranged on the top of supporting bracket; Described case lid is corresponding with the shape of casing, and described radiating fin is connected to the bottom of case lid by connecting plate, and in radiating fin, circulation is interspersed with oxygen-free copper pipe, and the two ends of oxygen-free copper pipe lead to case lid outside respectively.

Described casing top place is provided with equally distributed semicircle through wires hole, and on case lid, corresponding position is also provided with semicircular through wires hole, the conglobate through wires hole of semicircle orifice group corresponding after case lid and casing fasten.

Dividing plate is provided with, the impact that the heat distributed for cutting off transformer causes electric component between described transformer and electric component.

Described dividing plate has the window for interspersed connection electric wire.

The utility model adopts technique scheme to have following beneficial effect:

1, equipment adopts split type structure, and transformer device can take off separately, install separately, alleviates the total quality of equipment, install and carrying also comparatively before equipment more convenient;

2, the number of installing transformer device can be selected according to actual needs, convenient flexibly;

3, in casing, splendid attire cold oil adopts oxygen-free copper pipe and radiating fin jointly to coordinate heat radiation, and the coolant in oxygen-free copper pipe can realize at outside other equipment external of casing.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of casing and intraware.

Fig. 2 is the schematic diagram of case lid.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

Split type oil-cooled transformer group, it comprises casing 1, case lid 2, oxygen-free copper pipe 3, radiating fin 4, supporting bracket 5, transformer 6, electric component 7.

Casing 1 is as shown in Figure 1 square channel-shaped structure, is provided with the draw-in groove 11 of strip in casing 1 two bottom sides corner; Described supporting bracket 5 both sides can be fastened in the draw-in groove 11 bottom casing 1 accordingly, and described transformer 6 and electric component 7 are arranged on the top of supporting bracket 5; Case lid 2 is as shown in Figure 2 corresponding with the shape of casing 1, and described radiating fin 4 is connected to the bottom of case lid 2 by connecting plate 21, and in radiating fin 4, circulation is interspersed with oxygen-free copper pipe 3, and the two ends of oxygen-free copper pipe 3 lead to case lid 2 outside respectively.

Casing 1 top place is provided with equally distributed semicircle through wires hole, and on case lid 2, corresponding position is also provided with semicircular through wires hole, and case lid 2 and casing 1 fasten the rear corresponding conglobate through wires hole of semicircle orifice group.

Dividing plate 8 is provided with, the impact that the heat distributed for cutting off transformer 6 causes electric component 7 between transformer 6 and electric component 7; Dividing plate 8 has the window 9 for interspersed connection electric wire.

In the process used, the assemblies such as casing, case lid, transformer, electric component all dispersible and transport, then install in field of employment, determine the quantity of the transformer that will choose according to actual needs, then bottom half is contained in by supporting bracket, then connect up, finally case lid is buckled in the top of casing, after fixedly completing, add cold oil; The entrance point of oxygen-free copper pipe and the port of export are connected respectively to coolant recycle unit, can effectively be sent by the heat that cold oil absorbs in the process used.
