Fuse switch is arranged on 10KV distribution line branch line, can dwindle power failure range, because it has an obvious cut-off point, possess the function of isolating switch, create a safety work environment to maintenance section circuit and equipment, increased maintainer's the sense of security.Be arranged on distribution transformer, can be used as the main protection of distribution transformer, so, in 10KV distribution line and distribution transformer, obtained universal.
At present, disclose the fuse switch that a kind of application number is CN201320675560.8 on market, comprise insulator, cartridge fuse, has fixture on the support arm that stretch out described insulator top; Described cartridge fuse top is provided with bronze casting and draw ring, and bronze casting top is connected with the support arm that stretch out insulator top; Described cartridge fuse below is provided with bronze casting, and bronze casting right side arranges hinged bolt, and hinge bolt is connected with the support arm that stretch out insulator below; Described cartridge fuse upper and lower bronze casting other end is provided with stainless steel spring.By the design to fuse switch each several part high-quality, make product weatherability, water conservancy diversion failure on-off ability, load connecting-disconnecting function better, in the process of using, more there is safety guarantee.
But one end that the cartridge fuse of this fuse switch is connected with moving contact, be designed with the vertical operation ring being fixed on cartridge fuse, at needs, open a sluice gate, during closing operation, often need the hand-held long picaroon of operator, by the cleek hook of the pole other end enter operation ring carry out drop-down or on push work, and fuse installation requirement more than 5.5 meters, so this operation just has suitable difficulty, is wasted the plenty of time where necessary apart from bottom surface.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of use stock to open and close lock and operates also fuse switch very easily.
For achieving the above object, the utility model provides following technical scheme: a kind of fuse switch of handled easily, comprise post insulator and cartridge fuse, described post insulator two ends are respectively arranged with for the top electrode connecting plate of wiring and bottom electrode connecting plate, the support that is provided with gudgeon and is flexibly connected with one end of cartridge fuse on described bottom electrode connecting plate, on described top electrode connecting plate, be electrically connected with static contact, described cartridge fuse is provided with away from one end of support the pressure releasing cap being electrically connected to static contact, on described cartridge fuse, be fixedly connected with operating portion, wherein, described operating portion is the opening of hook formation setting and described hook-shaped operating portion towards static contact, described hook-shaped operating portion is arranged on cartridge fuse away from a side of post insulator.
By adopting technique scheme, to being arranged on the fuse of the 5.5 meters of height in code distance bottom surface, carrying out switching when operation, only need to use the hook portion of stock to ride on described operating portion, just can carry out the drop-down operation of opening a sluice gate, use the hook portion of stock to withstand on the operating portion below lock of just can slippaging above, the alignment function ring that do not need to require great effort again carries out switching operation
The utility model is further set to: on operating portion, be provided with inserting of being made by magnetic material.
By adopting technique scheme, when operating at a distance, inserting that described magnetic material is made can produce suction to the cleek on stock, and operator can be operated operating portion location more easily.
The utility model is further set to: described operating portion surface is provided with antirust coat, and posts fluorescence labels.
By adopting technique scheme, thereby guaranteed that operating portion can not tan by the sun because of outdoor wind and rain that being corroded gets rusty and come off damages, fluorescence labels can make operator facilitate and when night time operation, observe the position of operating portion.
The utility model is further set to: described static contact top is provided with protective cover, and described protective cover inside is provided with reinforcement.
Pass through technique scheme; described protective cover plays arc extinguishing effect; and avoid on rainy day; static contact and pressure releasing cap are subject to the erosion of rainwater; cause static contact and pressure releasing cap to get rusty or loose contact, even cause short circuit, circuit is produced to harmful effect; reinforcement another protective cover intensity improves, and prevents under the bad weather environmental aspects such as strong wind, hail along bad.
