Abstract

The utility model relates to a secondary safety measure isolator which comprises a cone. A hole for inserting a secondary thread end is arranged inside the cone. An opening of the hole faces a larger end of the cone. One side surface of the cone is provided with a tapping hole which matches a screw for reliably crimping the secondary thread end. A smaller end of the cone is fixed with a centre convenient for isolating a good secondary thread end to be connected to a terminal again. The cone, the centre and the screw are all prepared from an insulating material. The secondary safety measure isolator is prepared from the insulating material. Technically, operation safety is guaranteed, zero fault of operation is realized, and reliable economical and safety benefits are obtained. It is convenient to directly insert a secondary thread end and completely sealingly fix the secondary thread end, and the original terminal also can be connected back. The isolator provided by the utility model is safe and beautiful, is convenient to operate, and can be widely applied in relay protection, automation and instrument secondary systems.

Description

Secondary safety measure isolator
Technical field
The utility model relates to a kind of electric power safety measure spacer assembly, particularly a kind of secondary safety measure isolator that is exclusively used in secondary the end of a thread.
Background technology
Electric power system electrical secondary system is a complicated system, secondary cable the end of a thread quantity is countless, in installing at the scene, debug, safeguarding, need on operational outfit or repair apparatus, remove a large amount of secondary circuits, to reach repair apparatus and operational outfit isolation, guarantee not affect operating equipment.All the time, each professional, after dismantling secondary circuit, adopts electrician's glue wrapping the end of a thread, and this simple process mode exists following problem: 1, wrapping imprecision, because the great majority of secondary the end of a thread own are 1.5MM and 2.5MM, line is little easily to come off.2, the end of a thread majority is with strong voltage, easy error shock in wrapping process.3, the end of a thread part produces sharp parts in distribution, thin may being punctured of adhesive plaster and lose buffer action.4, throw away the end of a thread fixing nowhere, between line, distance or collide is short-circuited and ground connection together.Though secondary the end of a thread is little, but the unreachable position of safety measure is by system being produced to huge harm, greatly affects safe and stable operation.For many years, a lot of power grid accidents occurred in system, its reason is exactly the unreachable position of simple secondary circuit safety measure.
Utility model content
In order to eliminate the executory hidden danger of secondary safety measure, the purpose of this utility model is to provide a kind of secondary safety measure isolator, with secondary circuit in power production process, carries out safety measure, while carrying out secondary circuit isolation, prevents from touching by mistake.
To achieve these goals, the technical solution of the utility model is: a kind of secondary safety measure isolator, comprise cone, in described cone, be provided with for inserting the hole of secondary the end of a thread, the hole of described hole is towards the stub end of cone, the side opening of described cone is provided with tapping hole, described tapping hole is combined with the screw for reliable crimping secondary the end of a thread, the little head end of described cone is fixed with the nose heave thimble that newly takes back terminal of the secondary line of being convenient to isolate, and described cone, thimble and screw are made by insulating material.
Further, the hole diameter of described cone is 1.5mm ~ 4mm.
Further, the hole degree of depth of described cone is 2cm.
Further, described thimble diameter is 1.5mm, and length is 1.5cm ~ 2cm.
Further, the head of described screw is provided with and facilitates manual turncap.
Further, described secondary safety measure separator surface is provided with color coating.
Compared with prior art; the utlity model has following beneficial effect: this secondary safety measure isolator is made by insulating material; guaranteed technically the fail safe of operation; realize operation zero error; obtain economy and safety benefit reliably, facilitated secondary the end of a thread directly to insert and totally-enclosed fixing, also can take back former terminal; not only safety, but also attractive in appearance and handled easily, can extensive use in relaying protection, automation, instrument electrical secondary system.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the upward view of the utility model embodiment.
Fig. 3 is the left view of the utility model embodiment.
In figure: 1-cone, 11-hole, 12-tapping hole, 2-thimble.
Embodiment
As shown in Fig. 1 ~ 3, a kind of secondary safety measure isolator, comprise cone 1, in described cone 1, be provided with for inserting the hole 11 of secondary the end of a thread, the hole of described hole 11 is towards the stub end of cone 1, the side opening of described cone 1 is provided with tapping hole 12, described tapping hole 12 is combined with the screw (figure dispenses) for reliable crimping secondary the end of a thread, the little head end of described cone 1 is fixed with nose heave thimble 2(or the title aciculiform nose that newly takes back terminal of the secondary line of being convenient to isolate), described cone 1, thimble 2 and screw are made by insulating material.
In the present embodiment, this secondary safety measure isolator had both guaranteed that secondary cable core the end of a thread live part was all included in insulator, guaranteed fail safe, facilitates secondary the end of a thread is taken back to terminal under isolated instances again, kept attractive in appearance, convenient working.The hole diameter of described cone 1 is 1.5mm ~ 4mm, and described hole can be cylindrical cavity or conical hole, to be applicable to the connection of all secondary cable heart yearns, the size of secondary the end of a thread generally in 4mm, the cable core of 1.5mm ~ 4mm for example.The hole degree of depth of described cone 1 is 2cm, to be applicable to the end of a thread exposed metal/bare metal partial-length (being no more than 1.5cm) in actual field.
In the present embodiment, described thimble 2 diameters are 1.5mm, and length is 1.5cm ~ 2cm, adapt with the normal access digit of terminal, and its effect is by the nose heave terminal that newly takes back of the secondary line of having isolated, to guarantee the neat clear wash rice of secondary circuit.Owing to having countless terminals on secondary terminals row, if secondary the end of a thread is unfixing, will make secondary the end of a thread take and touch mutually, not attractive in appearance.
In the present embodiment, the head of described screw is provided with and facilitates manual turncap, without by other operation tools.This secondary safety measure isolator entire body adopts insulating material, and insulation is reliable, can prevent that secondary the end of a thread from puncturing, and for example thickness can bear copper core sharp object destruction, while preventing from touching with any charging equipment, gets an electric shock.In carrying out for safety measure to different function requirements: safety measure isolation, with red, is removed line with yellow temporarily, therefore corresponding isolator is also designed to Huang, the color such as green, red, such as secondary safety measure separator surface, is provided with Huang, the color coating such as green or red.
In the present embodiment, the using method of this secondary safety measure isolator is as follows: in the end of a thread metal partial insertion insulation cone 1 that secondary cable heart yearn is removed; Insulating screw on fastening cone 1 tapping hole 12 makes it secondary the end of a thread wherein carry out reliable crimping; Finally by thimble 2 by the nose heave terminal that newly takes back of the secondary line of having isolated.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
