Description
Technical field:
The utility model relates to electric elements technical field, is specifically related to a kind of plateau V-type BRD fuse.
Background technology:
Fuse (fuse) refers to when electric current exceedes setting, with the heat that itself produces, melt is fused, a kind of electrical equipment of open circuit.Fuse is after exceeding setting a period of time according to electric current, makes Melt molten, thus circuit is disconnected with the heat that himself produces; Use a kind of current protector that this principle is made.Fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment, as the protector of short circuit and overcurrent, is apply one of the most general protection device.Existing fuse is inconvenient in use, and useful life is short, complicated operation, fluctuation of service.
Utility model content:
The purpose of this utility model is to provide a kind of plateau V-type BRD fuse, and it is simple to operate, easy to maintenance, effectively solves the bad phenomenon that fault-free is fallen, stable, has the function of cut-offfing short circuit current, fault current.
In order to solve the problem existing for background technology, the utility model adopts following technical scheme: it comprises V-arrangement forging pedestal, composite insulator, external connection standard component, contact-support plate, pressure plate on contact, fixed contact spatula, fixed contact locking, upper contact moving contact, fusion tube sliding contact, glass fiber tube, lower contact geometrical clamp, lower slider contact, fixed contact padlock, conducting copper, two composite insulators are fixed by a pin on V-arrangement forging pedestal, one end of two composite insulators is separately installed with contact-support plate and conducting copper, the contact-support plate of wherein upper end is connected with pressure plate on contact in turn, fixed contact spatula, fixed contact locking, lower contact geometrical clamp, wherein fusion tube sliding contact, upper contact moving contact, glass fiber tube, lower contact geometrical clamp, lower slider contact constitutes right side fusion tube part, fusion tube sliding contact is closely fixed on glass fiber tube by pin, and lower slider contact is connected with lower contact geometrical clamp by rotating shaft, and lower slider contact is arranged in the copper hook of fixed contact padlock.
Described fusion tube is made up of the expulsion tube of internal layer and outer field glass fiber tube, and on it, moving contact is single contact, is blocked reach windproof effect by fixed contact locking, and lower moving contact is upset contact design mode.
Described composite insulator coupling part is precise steel casting.Lower contact geometrical clamp and lower slider contact are precision copper foundry goods.
The utility model is applicable to wind energy turbine set and the power station essential product as protection segmentation; be assemblied on distribution transformer high-pressure side or distribution wire branch circuit; only be used as transmission line, power transformer overload and short-circuit protection and deciliter rated load current; have simple to operate; easy to maintenance; the bad phenomenon that effective solution fault-free is fallen, stable, there is the function of cut-offfing short circuit current, fault current.
