Abstract
The utility model discloses a fuse section of thick bamboo for solid cabinet combined electrical apparatus cabinet, the device include the fusion tube, the inside fuse that sets up of fusion tube, the inside spring that sets up of fusion tube one end touches the finger, the spring touch the finger with fuse one end contacts each other, the spring touches and indicates the outside electrically conductive piece that sets up, the fusion tube other end sets up down electrically conductive piece, electrically conductive piece one end sets up firing pin mechanism down, seal supplementary earth bar admittedly through the oil blanket structure down on the electrically conductive piece, oil blanket structure upper portion sets up oil pressure balanced structure, go up electrically conductive piece, fusion tube and electrically conductive piece outside down and set up the insulating layer. The utility model discloses can effectively avoid present fuse direct mount internal in the cabinet, the fuse exposes and receives the environmental disturbance easily, exposes for a long time, and the problem that the contact resistance is big is changed.
Description
Technical Field
The utility model relates to a fuse section of thick bamboo technical field, in particular to solid cabinet makes up fuse section of thick bamboo for electric appliance cabinet.
Background
In the combined electrical appliance scheme used by the solid ring main unit, the combined electrical appliance and the fuse wire are usually adopted as a transformer protection scheme to achieve rapid switching-off and protect the transformer, but in the current scheme, a plurality of fuse wires are always exposed and directly installed in the main unit body, and the exposed fuse wires are easily interfered by the environment, exposed for a long time, contact resistance is increased, and various environmental factors often cause a plurality of problems.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a fuse section of thick bamboo for solid cabinet combined electrical apparatus cabinet can avoid present fuse direct mount internal in the cabinet, and the fuse exposes easily to receive the environmental disturbance, exposes for a long time, and the contact resistance changes big problem.
In order to achieve the above object, the technical solution of the present invention is specifically as follows:
the utility model provides a fuse tube for solid cabinet combined electrical apparatus cabinet, includes the fuse tube, the inside fuse that sets up of fuse tube, the inside spring that sets up of fuse tube one end touches the finger, the spring touch the finger with fuse wire one end contacts each other, the spring touches and indicates the outside electrically conductive piece that sets up, the fuse tube other end sets up down electrically conductive piece, electrically conductive piece one end sets up firing pin mechanism down, seal supplementary earth bar admittedly through oil blanket structure down on the electrically conductive piece, oil blanket structure upper portion sets up oil pressure balanced structure, go up electrically conductive piece, fuse tube and electrically conductive piece outside down and set up the insulating layer.
The insulating layer is an epoxy shell.
And a conductive layer is arranged outside the epoxy shell.
The utility model has the advantages that: the utility model discloses a set up the insulating layer at last electrically conductive piece, the fusion tube and electrically conductive piece outside down, play insulating purpose, avoided the fuse to expose the contact resistance that causes and change big security problem, wherein, for the insulating nature that improves the insulating layer, the insulating layer adopts the epoxy shell, for increasing the overhaul of the equipments security, the epoxy shell outside still is provided with the conducting layer, make whole outward appearance reliable ground, let equipment outside ground connection safe and reliable more, can also make the switch operation more stable as the inside electric field of shielding layer balanced switch.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The device comprises an epoxy shell, an upper conductive piece, a spring contact finger, a lower conductive piece, a striker mechanism, an auxiliary grounding rod, an oil seal structure, an oil pressure balance structure and an auxiliary grounding rod, wherein the epoxy shell comprises 1, 2, the upper conductive piece, 3, the spring contact finger, 4, the lower conductive piece, 5 and 6.
Detailed Description
As shown in fig. 1, a fuse tube for solid cabinet combined electrical apparatus cabinet, including fuse tube 9, the inside fuse that sets up of fuse tube 9, the inside spring that sets up of fuse tube 9 one end touches finger 3, spring touches finger 3 and fuse one end and contacts each other, spring touches finger 3 outside and sets up electrically conductive 2, the fuse tube 9 other end sets up down electrically conductive 4, 4 one end of lower electrically conductive sets up firing pin mechanism 5, seal supplementary earth bar 6 through oil blanket structure 7 admittedly on the electrically conductive 4 down, oil blanket structure 7 upper portion sets up oil pressure balanced structure 8, go up electrically conductive 2, fuse tube 9 and the electrically conductive 4 outside of lower electrically conductive set up the insulating layer, the insulating layer is epoxy shell 1, epoxy shell 1 outside still is provided with the conducting layer.
The utility model discloses when using, because whole outside parcel covers epoxy shell 1 for the fuse can not expose outside, has avoided the fuse to contact each other with various compositions in the air, takes place the oxidation scheduling problem, causes the contact resistance to change big security problem, overhauls the security for the improvement, 1 outside recoating of epoxy shell is brushed the conducting layer, but make whole organism ground connection, let equipment outside ground connection safe and reliable more, can also regard as the inside electric field of shielding layer balanced switch to make the switch operation more stable.
