Abstract
The utility model relates to a small fuse-contactor combined electrical appliance which comprises fuses, a contactor, conductive arms and a control module; the fuses, the contactor, the conductive arm and the control module are arranged on an insulator support; the insulator support is arranged on a chassis vehicle; a built-in conductor subsequently connects an upper conductive arm, the fuses the conductor and a lower conductive arm to form the combined electrical appliance. The three fuses are arranged at independent intervals, and the operation is simple and convenient. An electrified body is sealed in the insulator support, which ensures electrical insulation and makes sure the electrical appliance is not affected by outside environment, reduces the dimension (L*W*H:730*220*667) and realizes the small size and no maintenance of the product.
Description
Technical field
The utility model relates to the fuse-contactor combined electrical apparatus in a kind of high-voltage switch electric appliance, especially for the fuse-contactor combined electrical apparatus on the handcart in the nuclear power station nuclear 1E level electric equipment.
Background technology
At present, the high pressure power consumption equipment of the 50Hz of frequent operation, 7.2KV electric pressure, especially for 1000MW level nuclear power station fuse-contactor combined electrical apparatus, general width 〉=500mm, fuse adopts transverse arrangement of turbo, and mechanical endurance, electric life are lower than 100000 times; The branch of operating mechanism, close action and directly connect the divide-shut brake loop by power supply and send instruction, in case overvoltage or overcurrent are easy to cause the damage of branch, closing coil.
The utility model content
The utility model aim to provide a kind of take up room little, peak withstand current is bigger, and is not fragile, fuse-contactor combined electrical apparatus that useful life is bigger.
The utility model comprises fuse, contactor, last conductive arm, following conductive arm, control module, fuse, contactor, last conductive arm, following conductive arm, control module are installed on the insulating support, and insulating support is installed on the car of chassis, and built-in conductor will be gone up conductive arm, fuse, contactor successively, conductive arm connects into combined electrical apparatus down.
Described built-in conductor is enclosed in the insulating support admittedly.
Described insulating support is the molding for epoxy resin body.
Fuse of the present utility model is installed on respectively independently at interval, installs simple and easyly, changes and makes things convenient for; Fuse horizontal positioned, the fusion tube minimum that meets with stresses has effectively guaranteed life-span of fuse; Operating mechanism is simple and reliable, can realize that machinery keeps, electricity keeps, and mechanical endurance, electric life can reach 300000 times; The branch of operating mechanism, close action and control, bad power supply is controlled and compensated by power module, to minute, closing coil plays a very good protection.
Electrified body is encapsulated in the insulating support admittedly, guaranteed electric insulation, be not affected by the external environment, and reduced the overall dimensions (L * W * H:730 * 220 * 667) of combined electrical apparatus, realize the miniaturization of product and non-maintaining, thereby also dwindled the width of device for switching cabinet.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: the last conductive arm of 1-, 2-insulating support, 3-fuse, conductive arm under the 4-, 5-contactor, 6-chassis car, 7-control module.
Embodiment
As shown in Figure 1, 2, insulating support 2 is arranged on the chassis car 6, three fuses 3 are placed in respectively in the unique spacer on the insulating support 2, a contactor 5, three also are installed on the insulating support 2 go up conductive arm 1, three following conductive arms 4, the interior electric conductor of support is gone up each conductive arm 1, fuse 3, contactor 5 successively mutually, conductive arm 4 is connected to form the galvanic circle down admittedly be enclosed in, and the cylinder that the circumferential section of upper and lower conductive arm is insulated on the support 2 surrounds.Because current-carrying part is enclosed in the insulating support admittedly or is insulated material and surrounds, and has guaranteed electric insulation, has not been affected by the external environment, and reduced the overall dimensions (L * W * H:730 * 220 * 667) of combined electrical apparatus, realized the miniaturization of product and non-maintaining.Control module 7 also is housed on the insulating support 2, the branch of operating mechanism, closes action and control, bad power supply is controlled and compensated by power module, to minute, closing coil plays a very good protection.The insulating support of present embodiment is formed by epoxy resin APG cast, certainly, also can be made by other insulating material.
