Abstract
A high-voltage wiring device for a voltage transformer used on a combined electrical apparatus is convenient to assemble and has reliability in transportation. The high-voltage wiring device mainly comprises an insulator, a shielding cylinder, a lead, a fastening piece, a conducting rod, a coil shielding case and the like. The shielding cylinder is fixed on a center conductor of the insulator; one end of the lead is connected with the center conductor of the insulator, and the other end of the lead is fixed at the upper end of the conducting rod; and the lower end of the conducting rod is fixed on the coil shielding case. By adopting the wiring device, the center conductor of the insulator and the coil shielding case can be isoelectrically connected through the conducting rod and the conducting wire, and the structural flexible connection can effectively reduce failures such as vibration abrasion and invalidation of an electrode when equipment is being transported, so as to improve the reliability of electrical connection.
Description
(1) technical field
The utility model relates to a kind of combined electrical apparatus with voltage transformer high-voltage connection device, is used to realize that the insulator center conductor is connected with the equipotential of coil radome, belongs to power equipment and is electrically connected the field.
(2) background technology
At present, the matched voltage transformer of metal enclosed combined electrical apparatus, conventional structure is to adopt spring, contact, contact base is realized being electrically connected of insulator center conductor and coil radome, contact and contact base are realized the Elastic Contact of the two under the elastic force effect of spring, the perfect rigidity of being unrealized connects, the vibration friction can appear in contact and contact base in transportation, the vibration friction causes contact and contact base wearing and tearing, be electrically connected herein and have the hidden danger that lost efficacy, fricative metal dust is scattering into device interior, it is defective to cause equipment office to put easily, even the insulation breakdown explosion accident, influences the safe operation of equipment.
(3) summary of the invention
In order to overcome the defective on the existing combined electrical apparatus usefulness voltage transformer connecting structure for electrical equipment, the utility model provides a kind of high-voltage connection device of new construction, this termination is not only easy to assembly, realize being flexible coupling by lead, there be not contacting of metal parts and metal parts, can effectively avoid occurring in the transportation vibration friction and cause being electrically connected hidden danger such as inefficacy, improve the reliability that is electrically connected of equipment, guarantee the safe operation of equipment.
The technical scheme that its technical problem that solves the utility model adopts is: mainly be made up of insulator, shielding cylinder, lead, securing member, conducting rod, coil radome etc., shielding cylinder is fixed on the center conductor of insulator, lead one end is connected on the center conductor of insulator, the other end is fixed on the conducting rod upper end, and the conducting rod lower end is fixed on the coil radome.The center conductor of insulator carries out equipotential with the coil radome by conducting rod and lead and is connected.
The beneficial effects of the utility model are, realize being flexible coupling by lead, have solved original structure and have occurred the vibration friction in transit and cause being electrically connected multiple hidden danger such as inefficacy, and simple in structure, parts are easy to process, and are convenient for assembly, are electrically connected the reliability height.
