Abstract
The utility model relates to high-voltage end lead connection equipment, in particular to a high-voltage flexible connection device of a dry-type transformer, and the device is matched and used with the high-voltage connection end of the epoxy-cast dry-type transformer. Through using the high-voltage flexible connection device, the outgoing line connecting mode of the high-voltage end of the dry-type transformer does not follow the traditional connection mode of conventional bare extraction by a copper-embedded member matched with a screw rod, but the insulator of the epoxy high-voltage end of the dry-type transformer and the internally conical socket of a high-voltage cable are dexterously treated by one-time epoxy casting, are fused together, and then are extracted through a high-voltage flexible cable by using an internally conical insertion type cable terminal. Therefore, the high-voltage end of the dry-type transformer does not have a bare conductor so as to meet the requirements of complete sealing and insulation; and the comprehensive insulation level of a dry-type transformer product is increased to reduce the occupied space used for product installation.
Description
Technical field
The utility model relates to high-pressure side lead-in wire connection device, particularly a kind of dry-type transformer high pressure soft connection device, the supporting use of high-voltage terminal of this device and epoxy casting formula dry-type transformer.
Background technology
The dry-type transformer of epoxy casting has a series of excellent properties, particularly better fire prevention, explosion-proof, moistureproof, mildew-resistant, prevents characteristics such as salt fog, low noise, pollution-free, safety and reliability.Make dry-type transformer can go deep into load center, satisfy the various demands of user equipment for power transmission and distribution, thereby by wide popularization and application.In recent years along with the developing rapidly of complete high voltage switchgear, dry-type transformer many occasions all with switch cubicle, the supporting use of box-type substation, this has proposed renewal, higher requirement to dry-type transformer.
In the prior art, the dry-type transformer high-voltage connection terminal adopts through copper insert joins the exposed mode of connection of drawing of screw rod, the high-pressure side energized conductor is directly exposed outside, in order to guarantee the electrical safety clear distance of product, will keep bigger space around the exposed high-voltage connection terminal.
The utility model content
The purpose of this utility model is to provide a kind of can realize dry-type transformer high pressure soft connection device totally-enclosed, that all insulation connects.
The purpose of this utility model is achieved through the following channels: a kind of dry-type transformer high pressure soft connection device, the high-pressure side of dry-type transformer is connected with high-tension cable inner cone socket, high-tension cable inner cone socket is wrapped with epoxy high-pressure side insulator, connects high-voltage flexible cable with the inner cone plug-in cable termination of high-tension cable inner cone socket and coupling.
Further, inner cone plug-in cable termination and high-tension cable inner cone socket are fixed with set bolt by the flange on the epoxy high-pressure side insulator.
Further, the sidewall of epoxy high-pressure side insulator is a corrugated.
The utility model dry-type transformer high pressure soft connection device has following advantage:
1. the dry-type transformer high-pressure side does not have any exposed position, becomes totally-enclosed, all insulation structure.Improved the insulation level of dry-type transformer product integral body, made the dry-type transformer operation more safe and reliable;
2. shorten the dry-type transformer high-pressure side and the clearance of framework on every side, reduced the occupation of land space that dry-type transformer is installed;
3. dry-type transformer HV Terminal lead-in wire is owing to adopt the plug-in cable termination mode that is flexible coupling, so the transformer lead convenient disassembly is convenient to that product is installed, test and overhauling.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model user mode schematic diagram;
Among the figure, high-tension cable inner cone socket 1, inner cone plug-in cable termination 2, high-pressure side insulator 3, flange 4, high-voltage flexible cable 5, set bolt 6, dry-type transformer 7.
Embodiment
As shown in Figure 1 and Figure 2, the utility model dry-type transformer high pressure soft connection device, the high-pressure side of dry-type transformer 7 is connected with high-tension cable inner cone socket 1, high-tension cable inner cone socket 1 is wrapped with epoxy high-pressure side insulator 3, the sidewall of epoxy high-pressure side insulator 3 is a corrugated, connect high-voltage flexible cable 5 with high-tension cable inner cone socket 1 and the inner cone plug-in cable termination 2 that mates, inner cone plug-in cable termination 2 is fixing by the 4 usefulness set bolts 6 of the flange on the epoxy high-pressure side insulator 3 with high-tension cable inner cone socket 1.
The utility model dry-type transformer high pressure soft connection device adopts the high-voltage flexible cable 5 of two ends tape cable inner cone plug-in terminal 2 to connect, and high-voltage flexible cable 5 one ends link to each other with the high-pressure side of dry-type transformer 7, and the other end links to each other with the SF6 air chamber of GIS switch cubicle.By using the utility model, the outlet connected mode of dry-type transformer high-pressure side, that does not follow routine joins the exposed traditional wired mode of drawing of screw rod through copper insert, but dexterously with the epoxy high-pressure side insulator 3 and high-tension cable inner cone socket 1 disposable epoxy casting of dry-type transformer 7, merge, draw through high-voltage flexible cable 5 with inner cone plug-in cable termination 2 again.Thereby make the high-pressure side of dry-type transformer 7 not have bare exposed conductor, reach requirement totally-enclosed, all insulation.Improve the insulation level of dry-type transformer product integral body, thereby reduced the occupation of land space that product is installed and used.
