Problems solved by technology

Traditional transformers are usually directly designed as core-type transformers or shell-type transformers when designing. Different transformers are directly selected according to different usage conditions. However, in power tests or other situations that require voltage and current conversion , people often have to change the type of transformer, and the operation is not convenient enough

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0016] like figure 1 , figure 2 , image 3 and Figure 4 As shown in the embodiment, this articulated adjustable transformer includes a main iron core 1 and an auxiliary iron core 2, the main iron core 1 and the auxiliary winding core 2 are connected as a whole through the upper connecting piece, A vertical main coil 3 is wound, and a vertical secondary coil 4 is wound on the secondary iron core 2. The main coil 3 is divided into front and rear parts from the middle vertical surface. The front and rear parts of the main coil 3 are The main coil 3 is partially hinged. The front and rear parts of the main coil 3 are hinged separately on one side. The front and rear parts of the main coil 3 are in close contact with each other. The adjustment shafts 5 used in pairs are fixedly connected, and the adjustment shafts 5 are hinged with pull rods 51 protruding from th...

Abstract

The invention provides an articulated adjustable transformer. The articulated adjustable transformer comprises a main iron core and a secondary iron core which are connected into a whole through a connecting sheet arranged on the upper portion, the main iron core is wound with a vertical main coil, and the secondary iron core is wound with a vertical secondary coil; the main coil is divided into a front portion and a back portion from the middle vertical face, the front portion and the back portion of the main coil are hinged and fixedly connected through front adjusting shafts and back adjusting shafts which are used in pairs respectively, and the adjusting shafts are hinged to pull rods which stretch out to wrap a shell; horizontal metal strips are connected to the front hinged positions and the back hinged positions of each ring of the main coil and fixed to an electric connecting block. The transformer can adjust the voltage alternation ratio and is higher in transformer efficiency; meanwhile, the type of the transformer can be changed to adapt to the service condition of different kinds of circuits.

Description

Technical field [0001] The invention belongs to the technical field of transformers, in particular to a hinged adjustable transformer. Background technique [0002] The transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It can boost the low-voltage electricity and transmit it, and can also reduce the high-voltage electricity and deliver it to the user, which is convenient for the use of ordinary electrical appliances. , The transformer is mainly composed of iron core, winding, oil tank, oil pillow, insulating bushing, tap changer and gas relay. According to the different transformer occasions and the specifications of the transformer circuit, there are many types of transformers. In order to make the transformer easy to adjust, different connection points are often designed on the transformer windings that people often use, or sliding connections are used to make the transformat...
