Abstract
The utility model discloses a transformer capable of conducting double-voltage input or output. The transformer capable of conducting double-voltage input or output comprises a coil. The coil is provided with a plurality of connectors, each connector is connected with a conducting rod, and the functions of series connection and parallel connection or middle voltage tap leading out of the conducting rods are achieved through conducting switching boards. The transformer further comprises wires. The wires are connected with the conducting rods and the coil at the same time so that the output end of the transformer can be formed. Due to the switch of the conducting switching boards on the conducting rods, series connection and parallel connection of the coil can be achieved or the middle voltage tap leading out is achieved. Therefore, input voltage or output voltage is of two different types. The transformer capable of conducting double-voltage input or output is simple in overall structure, convenient to operate and capable of satisfying the actual requirements.

Technical field
The utility model relates to a kind of transformer, particularly a kind ofly realizes the voltage connection in series-parallel or has with tapped a transformer that two voltage inputs or outputs.
Background technology
Along with the adjustment of electric power system and user's operating mode upgrading with change, in order to continue to meet and to adapt to the adjustment of line voltage and be unlikely to waste existing equipment later, more and more transformer requirement realization pair voltage inputs or outputs.As low pressure output can realize string between 21kV and 10.5kV-conversion in parallel, inputing or outputing 35kV can arise at the historic moment with the new demands such as intermediate voltage tap of 21kV.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of transformer that two voltage inputs or outputs that has, and realizes inputing or outputing the voltage of two kinds of forms.
The technical scheme that the utility model adopts is:
A kind of have a transformer that two voltage inputs or outputs, and described transformer includes coil, and described coil has a plurality of joints, and each joint is connected with conducting rod, between described conducting rod by conduction switch boards serial or parallel connection; Described transformer further includes wire, thereby this wire is connected the output that forms transformer simultaneously with coil with conducting rod.
Described conducting rod is fixed on insulated fixing support.
Described conducting rod is fixedly connected with insulated fixing support by securing member.
Described transformer tank covers and offers handle hole, and described conducting rod is positioned under handle hole.
Compared with prior art, the utility model at least has following beneficial effect: the utility model is realized series connection or in parallel by the conduction switch boards by conducting rod, thereby makes the voltage inputed or outputed can have two kinds of different forms.Overall structure is simple, easy to operate, practical requirement.
The accompanying drawing explanation

Embodiment
In order to meet the two voltage market development requirements of transformer with rapid changepl. never-ending changes and improvements, realize that string-conversion in parallel can adopt change over switch to realize, the intermediate voltage tap can adopt and lead-and disconnects and closing or the increase sleeve pipe such as directly draws at the scheme realization.The purpose of this utility model is: without adopting conversion or leading-disconnect pass, invent a kind of simple, reliable, safe, economic new construction.Realize inputing or outputing of two voltages.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
Open one of three every phase of handle hole 1(on transformer oil tank cover), under being caused to handle hole 1, also reliably fix all terminals that need to switch or connect, utilize the conducting rod wiring, the switching short-circuit board is cut off and conducting, simple to operate, reliable, safety.
Switch solution is installed in employing additional, has increased fuel tank volume and cost, and two voltage transformer voltage switching times are few, so there is no need to install additional switch; The intermediate voltage tap adopt to increase sleeve pipe and directly draws scheme, has increased external cabling and insulation difficulty, and wants rewiring during the voltage switching, and unnecessary difficulty has been brought in the aspects such as transformer operation and maintenance.Contrast, adopt the utility model structure, and economy is better.
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
A kind of have a transformer that two voltage inputs or outputs, and described transformer includes coil, and described coil has a plurality of joints, and each joint is connected with conducting rod, between described conducting rod by conduction switch boards 2 serial or parallel connections; Described transformer further includes wire, thereby this wire is connected the output that forms transformer simultaneously with coil with conducting rod.
Described conducting rod is fixed on insulated fixing support 3, and described conducting rod is fixedly connected with by fixing 3 of securing member and insulation.
Refer to shown in Fig. 1 to Fig. 6, open the handle hole 1 that transformer tank covers, turn on the securing member on corresponding conducting rod, according to the operation mark on Fig. 3 and Fig. 6, with conduction switch boards 2 conductings or disconnect each current-carrying conducting rod, realize that needed voltage inputs or outputs.
The utility model when design should be noted that following some: conducting rod design: guarantee current-carrying size and insulation distance;
2. overall structure will be fixed reliably;
3. global design will make to conduct electricity switch boards conducting or simple to operate, reliable, safety while disconnecting each conducting rod.
The utility model has been realized voltage string-parallel connection or has been with tapped pair of voltage to input or output function in a kind of the most simple, reliable, safe, economic new construction mode, without using other modes such as switch, sleeve pipe, make transformer device structure more compact, save the occupation of land space, greatly reduced cost; With many sleeve pipe lead-out modes of band intermediate voltage tap, compare, its all suspended voltage terminals seal entirely in fuel tank, and the security reliability of having avoided sleeve pipe to draw is poor, safeguard and the phenomenons such as the voltage switching is difficult.
The utility model can extend to the structures such as multivoltage output.
