Abstract
A large current balance output device of double-disc coils is arranged in the housing of a transformer. The output device consists of double-disc coils, connectors, a copper bus bar and cable entries. The output device is provided with multiple groups of double-disc coils, each group of double-disc coils is provided with two connectors, one of the connectors is marked with a, and the other connector is marked with X. Multiple connectors of the double-disc coils are arranged on the copper bus bar, and cable entries on one end of the copper bus bar extend out of the housing and are sealed by seal rings. The connectors of the double-disc coils, which are connected to the copper bus bar, are not arranged in a symmetrical way. Part copper bus bar is connected with multiple connectors, and part copper bus bar is connected with few connectors. Current on the copper bus bar can be adjusted to make the current uniformly distributed on the copper bus bar by adjusting the number of connectors on the copper bus bar, so the copper bus bar is heated uniformly. The problem that part copper bus bar is excessively heated, which results in quick aging, and influences the service life of the transformer is solved.
Description
Technical field
The utility model belongs to technical field of transformer manufacturing, relates to a kind of pair of big current balance type output device of disc coil.
Technical background
In prior art, the output device of two disc coil strong current transformers is installed in the transformer casing, by two disc coils, connector, outlet copper bar and leading-out terminal are formed, two disc coils have many groups, one group of two disc coil connector has two, a mark is a, another mark is X, and two disc coil connectors are connected on the outlet copper bar, and the connector of a mark is contained on a slice copper bar, the connector of X mark is installed on another sheet copper bar, outlet copper bar one end is equipped with leading-out terminal, and one of leading-out terminal is stretched out outside the casing, seals with sealing ring, be connected the two disc coil connectors on the outlet copper bar, on each copper bar, evenly arrange.This connected mode, because the CURRENT DISTRIBUTION in the transformer on the double-cake coils is inhomogeneous, electric current is big on the coil that has, electric current is little on the coil that has, after being connected on the copper bar, cause the current unevenness on each copper bar even, cause the caloric value of each copper bar inhomogeneous, make heating excessive copper bar quick aging, damage easily, influence the useful life of whole transformer.
Technical scheme
The utility model is at problems of the prior art, a kind of pair of big current balance type output device of disc coil is provided, this device is installed in the transformer casing, by two disc coils, connector, outlet copper bar and leading-out terminal are formed, two disc coils have many groups, one group of two disc coil connector has two, a mark is a, another mark is X, and two disc coil connectors are connected on the outlet copper bar, and the connector of a mark is contained on a slice copper bar, the connector of X mark is installed on another sheet copper bar, outlet copper bar one end is equipped with leading-out terminal, and one of leading-out terminal is stretched out outside the casing, seals with sealing ring; Be connected the two disc coil connectors on the outlet copper bar, be asymmetric arrangement, the connector on the part copper bar is many, and the connector on the part copper bar is few.
Adopt this technical scheme, can regulate the electric current on the copper bar by regulating the quantity of outlet copper bar upper binding head, electric current on the copper bar is tended to balance, the heating of copper bar is tended to balance, thereby avoid the part copper bar because of generating heat too much, quick aging influences the transformer problem in useful life.
In the real work, common double disc coil strong current transformer, there be the phenomenon of the output current of middle part coil greater than both sides coil output current, for making the technical program and general applicability being arranged, the two disc coil connectors that on the outlet copper bar, connect, can be arranged on the copper bar at middle part more, be arranged in less on the copper bar on both sides.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Execution mode
Embodiment: as shown in Figure 1, the big current balance type output device of two disc coils, be installed in the transformer casing 6, by two disc coils 1, connector 2, outlet copper bar 3 and leading-out terminal 4 are formed, two disc coils 1 have many groups, one group of two disc coil connector 2 has two, a mark is a, another mark is X, two disc coil connectors 2 are connected on the outlet copper bar 3, and the connector of a mark is contained on a slice copper bar, and the connector of X mark is installed on another sheet copper bar, outlet copper bar 3 one ends are equipped with leading-out terminal 4, one of leading-out terminal 4 is stretched out outside the casing 6, with sealing ring 5 sealings, is connected the two disc coil connectors 2 on the outlet copper bar 3, be asymmetric arrangement, connector on the part copper bar is many, and the connector on the part copper bar is few, and outlet copper bar 3 has four in the present embodiment, go up the two disc coil connectors 2 that connect from top to bottom respectively and be four, seven, six and three.
