Abstract
The utility model discloses a 10 kV outdoor high-voltage current limiting fuse. The fuse mainly comprises a contact base and a wiring board arranged on the contact base, wherein an end cover is arranged at one end of the contact base; a contact base end socket is arranged at the other end of the contact base; a buckling ring is arranged on the contact base end terminal; a porcelain sleeve bolt is arranged on the contact base end socket; an adjustment clip bolt is arranged on the wiring board; and the buckling ring is oblate. In the current limiting fuse, on the basis of an original high-voltage current limiting fuse, the end cover capable of rotating by 180 degrees is arranged on the contact base end terminal, and the buckling ring is additionally mounted at the closure part of the end cover, so that the open and the close are convenient and simple; the connection is convenient, and reusability is realized; the 10 kV outdoor high-voltage current limiting fuse has a simple structure, is convenient to install and use, can not damage equipment or lead wires, and can be replaced so long as the end cover is opened by one person without disassembly and assembly of any connecting parts; and the 10 kV outdoor high-voltage current limiting fuse has the characteristics of simple structure, convenience in use, safety and rapidness.
Description
Technical field
The utility model relates to a kind of electric power equipment, particularly relates to a kind of 10kv outdoor high-voltage current limiting fuse.
Background technology
At present; in the electric power system; no matter be the electrical circuit of small capacity transformer in power plant, the electric substation, voltage transformer, single electric equipment such as formula capacitor group; less for electric current under the above equipment normal operating conditions; in a single day when being short-circuited fault; because the impedance in its loop is less, thereby short circuit current is big especially, generally selects the overload or short-circuit protection of high-voltage and current-limitation fuse as power equipments such as motor, transformer, voltage transformer, capacitor groups.High-voltage and current-limitation fuse is applicable to and exchanges 50HZ, in rated voltage 3～10KV system, also can be used with other electrical equipment (as switch, contactor etc.),
In the actual motion of electrical network, owing to 10kv high-voltage and current-limitation fuse fuse failure phenomenon can often take place reasons such as fault, power network overvoltage, thunderbolt, strong wind, heavy rain, sleet during the equipment operation, maintainer's this moment power failure is in time repaired and is changed.But see that with practical conditions repairing more changes jobs exists following problems:
1, fuse is installed in the height more than 3.0 meters, the inconvenient maintainer replacing of ascending a height, and work high above the ground is dangerous big.
2; fused mass of fuse adopts the length of spring compressed assembling; the normal operation maintenance of inconvenience and more changing jobs on framework; in operation maintenance and changing; the maintainer will realize that melt more changes jobs; the fuse capping should be opened; because the fuse long term exposure is moved out of doors; expose to the weather, each connecting screw corrosion is serious, is difficult to dismounting; sometimes must adopt the hacksaw cutting; work difficulty is big; the replacing time is long, generally must be cooperated just by 2-3 people and can finish change of fuse work, causes interruption duration long; to protective relaying device; the metering device influence is very big, unfavorable power network safety operation work.
3, the reason of fused mass of fuse fusing is caused by thunderbolt, strong wind, heavy rain more than 90%, so change the work of fuse, all is to carry out at special weather basically, and difficulty is bigger.Because the existence of above-mentioned several reasons brings very big trouble for work about electric power person.
The utility model content
In view of this, the utility model provides a kind of 10kv outdoor high-voltage current limiting fuse, can make things convenient for to realize that simply fused mass of fuse changes fast, to overcome the deficiencies in the prior art.
The technical solution of the utility model realizes with following method,
A kind of 10kv outdoor high-voltage current limiting fuse, mainly by contact base, the terminal block that is arranged on the contact base constitutes, wherein, contact base one end is provided with end cap, also is provided with the contact base termination on the contact base other end, the contact base termination is provided with clasp, and the contact base termination is provided with the porcelain bushing bolt.
Terminal block is provided with the adjusting cable clip bolt.
Clasp is oblate.
The good effect of technical solutions of the utility model is,
The utility model is on the basis of original high-voltage and current-limitation fuse, is provided with a rotatable end cap of 180 ° on the touch base termination, and the closed place of end cap has installed clasp additional, thereby reaches the purpose of convenient simple and easy open and close; Easy to connect, can reuse; The utlity model has simple in structure, easy to install, do not damage equipment or lead, need not any link of dismounting, a people opens end cap just can finish change of fuse work.The utlity model has simple in structure, easy to use, safe, efficient characteristics.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further,
As seen from Figure 1, this 10kv outdoor high-voltage current limiting fuse, mainly by contact base 7, be arranged on the terminal block 1 on the contact base 7, constitute, wherein, contact base 7 one ends are provided with end cap 3, also be provided with contact base termination 5 on contact base 7 other ends, contact base termination 5 is provided with clasp 2, and contact base termination 5 is provided with porcelain bushing bolt 6.
As seen from Figure 1, terminal block 1 is provided with regulates cable clip bolt 4, and contact base termination 5 is connected with porcelain bushing by porcelain bushing bolt 6.
As seen from Figure 1, clasp 2 is oblate.
During use, high-voltage and current-limitation fuse is connected with other equipment by terminal block 1, and it is also locked to utilize clasp 2 to compress after end cap 3 sealings, and terminal block 1, end cap 3,5 contacts of contact base termination well constitute conductive channel, and end cap 3 seals with clasp 2 and prevents that melt from making moist; Start clasp 2 and can open end cap 3, make things convenient for melt to change, simple and easy, safe, quick.
Contact base termination 5 utilizes earthenware bolt 6 to fixedly connected with porcelain bushing, and end cap 3 and terminal block 1 are aluminium matter or copper die cast metal moulding, to strengthen conductivity.
Before the use, should use on the high-voltage and current-limitation fuse equipment, change or installation touch base termination, utilize the earthenware bolt to connect, be connected with equipment, only need open or seal in the real work by terminal block.
