Abstract
The utility model relates to a pin configuration of a combined type on-load tap-changer. The pin configuration is mainly used for the electrical connection of a selector switch of a combined type on-load tap-changer and a tap selector. The pin configuration comprises a connection plate, a leading wire and an insulation bearing. The insulation bearing used for fixing the leading wire to be static is arranged on the middle portion of the leading wire. The insulation bearing is fixed on the upper bearing of the tap selector through screws, and the connection plate is fixed with the selector switch. The upper end of the leading wire is connected to the connection plate, and the lower end penetrates through the insulation bearing and is fixed on the middle shaft of the tap selector. According to the pin configuration of the combined type on-load tap-changer, the insulation bearing used for fixing the leading wire to be static is set up on the middle portion of the leading wire, and therefore the possible accident potentials in a switch transportation process and in an assembling process in a transformer factory are avoided.
Description
Technical field
The utility model belongs to dynamo-electric manufacturing field, particularly a kind of pin configuration of combined loaded tap-changer.
Background technology
The pin configuration of combined loaded tap-changer is used for realizing the diverter switch of combined loaded tap-changer and electrically connecting of tap selector.
The pin configuration of existing combined loaded tap-changer comprises connecting plate, lead-in wire as shown in Figure 1.
Connecting plate is assemblied on the diverter switch leading point, and the lead-in wire upper end is connected on the connecting plate, and the lead-in wire lower end is fixed on the tap selector jack shaft.
Though the pin configuration of existing combined loaded tap-changer can be realized the diverter switch of combined loaded tap-changer and connecting of tap selector electricity, because there is following shortcoming in its reasons in structure:
1, adopt this kind structure, the lead-in wire processing difficulties of curvature of space, time-consuming, precision is difficult to guarantee that quality stability is not high;
2, the lead wire insulation layer of might the vibration in transportation damaging, and be not intended to pull the lead wire insulation layer of damaging in transformer factory's assembling, cause the decreasing insulating of whole switch, cause burning damage accident.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming of existing combined loaded tap-changer pin configuration, and the pin configuration of a kind of modified model combined loaded tap-changer that proposes.
A kind of pin configuration of combined loaded tap-changer, this pin configuration are mainly used in the diverter switch of combined loaded tap-changer and electrically connecting of tap selector; This pin configuration comprises connecting plate, lead-in wire, insulated leg; Middle part at lead-in wire is provided with the motionless insulated leg of anchor leg; Insulated leg is fixed on the upper bracket of tap selector by screw; Connecting plate and diverter switch tighten together; The upper end of lead-in wire is connected on the connecting plate, and its lower end is passed on the jack shaft that insulated leg is fixed on tap selector.
Because the utility model has adopted above technical scheme:
1, will go between and adopt the plain bending mode, processing technology is good, has realized that all lead-in wires can curve type with same secondary angle coupling tool, has guaranteed size and the shape of lead-in wire;
The motionless insulated leg of anchor leg is set up at the middle part that 2, will go between, issuable accident potential when having avoided switch to assemble in transportation and in transformer factory.
Description of drawings
Fig. 1 is the general illustration of the pin configuration of existing shunting switch;
Fig. 2 is the general illustration of the pin configuration of the utility model shunting switch;
Fig. 3 is that the lead-in wire of the utility model shunting switch is assemblied in the schematic diagram on the tap selector.
Embodiment
On load tap changer is a kind of component of high voltage electrical apparatus, is applied in the transformer, is a vitals of transformer, mainly plays regulation voltage.
Such as Fig. 2, shown in Figure 3, the pin configuration of a kind of combined loaded tap-changer of the utility model is used for the diverter switch 1 of combined loaded tap-changer and electrically connecting of tap selector 6; Described pin configuration comprises connecting plate 2 and lead-in wire 3, sets up the motionless insulated leg of anchor leg 4 at the middle part of lead-in wire; Wherein, lead-in wire 3 puts insulated leg 4 and assembles with tap selector 6, with screw insulated leg 4 is fixed on the upper bracket 5 of tap selector 6.Connecting plate 2 is assembled into one with diverter switch 1, and the upper end of lead-in wire 3 connects and is connected on the connecting plate 2, and 3 lower ends that go between are fixed on the jack shaft of tap selector 6.The diverter switch 1 of combined loaded tap-changer and electrically connecting of tap selector 6 have finally been realized.
The utility model lead-in wire processing technology is good, and switch insulation intensity is high, issuable accident potential when having avoided switch to assemble in transportation and in transformer factory.
