Description
Technical field
The utility model relates to transformer technology field, especially a kind of isolating transformer with warning device.
Background technology
The Main Function of isolating transformer is: primary side and the electric of secondary side are insulated completely, also makes this loop isolate.In addition, utilize the feature that the high-frequency loss of its iron core is large, thus suppress high frequency spurs to import control loop into.With isolating transformer, secondary is suspended over the ground, the occasion that supply district is less, circuit is shorter can only be used in.Now, the capacitive earth current of system is so little that to be not enough to damage the person, and also have a very important effect to be exactly protect personal safety, traditional isolating transformer cannot carry out fault detect, and transformer bad meeting of dispelling the heat causes temperature too high and is short-circuited.In addition, because isolating transformer loss is large, therefore require higher to its class of insulation, traditional insulating material result of use is not ideal enough.
Utility model content
The technical problems to be solved in the utility model is: for overcoming above-mentioned Problems existing, provide a kind of good insulating, the isolating transformer of the band warning device that efficiency is high.
The utility model solves the technical scheme that its technical problem adopts: a kind of isolating transformer with warning device, comprise metal shell and be housed in the three-phase transformer in metal shell, described metal shell to both sides be extended with draw pin and fixing described in draw the hermetic terminal of pin, described three-phase transformer connecting circuit detector, described circuit detector connects fault alarm, temperature measuring set connects fault alarm, described circuit detector, be connected in parallel between temperature measuring set, described circuit detector, temperature measuring set and fault alarm outside are all coated with polyester film, improve insulating properties, and good pressure-resistant performance, elementary lead-in wire is extracted out between described metal shell and three-phase transformer, described three-phase transformer lower end is welded with metal cover board.
Further, described elementary lead-in wire is polyester enamelled wire, conducts electricity very well, and has enough heat resistances, and has certain corrosion resistance.
Further, described elementary lead-in wire overcoat has silica gel glass fibre sleeve, can reduce its conductivity, completely reliably.
Further, outside described three-phase transformer, be coated with yellow varnished insulating cloth, more effectively can improve insulation property.
The beneficial effects of the utility model are, the isolating transformer of band warning device of the present utility model is provided with temperature measuring set and circuit detector, can automatic alarm when transformer breaks down, can, with the fastest mode find problem, increase work efficiency, and the class of insulation be high, effectively slow down iron loss and copper loss that the temperature rise due to transformer causes, easily manufactured, improve the operational reliability of transformer, use safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. metal shells, 2. three-phase transformer, 3. hermetic terminal, 4. circuit detector, 5. temperature measuring set, 6. fault alarm in figure, 7. elementary lead-in wire, 8. metal cover board.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The isolating transformer of band warning device as shown in Figure 1, comprise metal shell 1 and be housed in the three-phase transformer 2 in metal shell 1, metal shell 1 to both sides be extended with draw pin and fixing described in draw the hermetic terminal 3 of pin, three-phase transformer 2 connecting circuit detector 4, circuit detector 4 connects fault alarm 6, temperature measuring set 5 connects fault alarm 6, is connected in parallel between circuit detector 4, temperature measuring set 5.When temperature measuring set 5 detects that transformer temperature is too high, fault alarm 6 can send warning; When circuit detector 4 detects the failure problems such as circuit is short-circuited, the fault alarm 6 be connected with circuit detector 4 also can send warning, and staff can be investigated as early as possible and go wrong, convenient for maintaining, effectively improves operating efficiency.
In addition, all polyester film is coated with in circuit detector 4, temperature measuring set 5 and fault alarm 6 outside, improve insulating properties, and good pressure-resistant performance, elementary lead-in wire 7 is extracted out between metal shell 1 and three-phase transformer 2, three-phase transformer 2 lower end is welded with metal cover board 8, and metal cover board 8 can improve its heat dispersion.Elementary lead-in wire 7 is polyester enamelled wire, conducts electricity very well, has enough heat resistances, and have certain corrosion resistance.Elementary lead-in wire 7 overcoat has silica gel glass fibre sleeve, can reduce its conductivity, completely reliably.Be coated with yellow varnished insulating cloth outside three-phase transformer 2, more effectively can improve insulation property.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
