Abstract
The invention discloses a metal bulb used for a fiber composite insulator. The metal bulb comprises a metal bulb body. One end of the metal bulb body is provided with a pressure welding area which is cooperated with an insulator core rod. The insulator is the fiber composite insulator. The other end of the metal bulb body is provided with a tail fiber outlet which is communicated with the pressure welding area. According to the invention, through adding the tail fiber outlet on the metal bulb body, a tail fiber can pass through the metal bulb so as to form a loop to transmit a signal, and the metal bulb is simple in structure and is suitable for the fiber composite insulator. The tail fiber outlet is designed as a tapered sealing screwed hole to facilitate protection and sealing of a welding point of the tail fiber behind the outlet without being influenced by outdoor climate conditions. A tail fiber bending zone which enables bending transition of the tail fiber is added between the tail fiber outlet and the pressure welding area, a needed bending radius without breaking is provided for the tail fiber, the tail optical fiber passes through the tail fiber bending zone for buffer transition and is led out from the tail optical fiber outlet, and the tail fiber is not broken because of an overlarge bending angle. The metal bulb is suitable for the fiber composite insulator.
Description
Technical field
The present invention relates to the power circuit apparatus field, particularly a kind of optical fiber composite insulator is used hardware ball-head.
Background technology
Before the present invention proposed, composite insulator had obtained using widely on power system transmission line with good hydrophobicity and migration of hydrophobicity.Usually, excellent core one end of composite insulator is articulated on the power circuit through hardware ball-head.
Along with developing rapidly of optical fiber sensing technology, optical fiber in the application in composite insulator field also more and more widely.Optical fiber is implanted in the plug of composite insulator (formation optical fiber composite insulator), detected and transmit signal, can effectively monitor the stress and the variation of temperature of composite insulator in real time through optical fiber.Simultaneously, because light signal is not subject to characteristics such as electromagnetic environment influence, the optical fiber of implantation will not influence the application of composite insulator in hyperbaric environment.But because traditional hardware ball-head is not provided with the optical fiber outlet; So if use traditional hardware ball-head to articulate the excellent core of optical fiber composite insulator; Then tail optical fiber (a part of optical fiber of stretching from the termination of plug) will so just can not detect the stress and the temperature of composite insulator through optical fiber in real time in plug is sealed in hardware ball-head.
Summary of the invention
The objective of the invention is provides a kind of simple in structure in order to overcome the deficiency of above-mentioned background technology, is applicable to that the optical fiber composite insulator of optical fiber composite insulator is used hardware ball-head.
In order to realize above purpose; A kind of optical fiber composite insulator provided by the invention is used hardware ball-head; Comprise: the hardware ball-head body, said hardware ball-head body one end is provided with the crimp area that matches with the plug of insulator, it is characterized in that; Said insulator is an optical fiber composite insulator, and the said hardware ball-head body other end is provided with the tail optical fiber outlet that is connected with said crimp area.Through on the hardware ball-head body, adding the tail optical fiber outlet, tail optical fiber can from this gold utensil bulb, be passed, simple in structure so that form the loop transmission signals, be applicable to optical fiber composite insulator.
In such scheme, said tail optical fiber outlet is band tapering sealing thread hole.Like this, be convenient to protect and seal the weld of tail optical fiber after outlet, the reliability when having guaranteed sealing helps protecting the weld of tail optical fiber, and can not receive the influence of outdoor climate conditions.
In such scheme, be provided with between outlet of said tail optical fiber and the crimp area and can let the tail optical fiber buckled zone of tail optical fiber curve transition.Because said tail optical fiber has certain intensity, so, may cause tail optical fiber to fracture if the direct wide-angle bending of tail optical fiber is derived from the tail optical fiber outlet.Therefore, the tail optical fiber buckled zone that adds is that tail optical fiber provides the required bending radius that can not fracture, and like this, tail optical fiber is derived from the tail optical fiber outlet after cushioning transition through the tail optical fiber buckled zone again, just can not cause fractureing because of angle of bend is excessive.
In such scheme, the longitudinal length of said tail optical fiber buckled zone is 0.8～1.2 centimetre.Like this, tail optical fiber can not fracture or have very big loss when passing.
The beneficial effect that technical scheme provided by the invention is brought is: on the one hand,, tail optical fiber can from this gold utensil bulb, be passed through on the hardware ball-head body, adding the tail optical fiber outlet, and simple in structure so that form the loop transmission signals, be applicable to optical fiber composite insulator; On the other hand, the outlet of said tail optical fiber is designed to be with tapering sealing thread hole, is convenient to protect and seals the weld of tail optical fiber after outlet, the reliability when having guaranteed sealing helps protecting the weld of tail optical fiber, and can not receive the influence of outdoor climate conditions; At last; Between outlet of said tail optical fiber and crimp area, add and to let the tail optical fiber buckled zone of tail optical fiber curve transition; For tail optical fiber provides the required bending radius that can not fracture, like this, after tail optical fiber cushions transition through the tail optical fiber buckled zone; Derive from the tail optical fiber outlet again, just can not cause fractureing because of angle of bend is excessive.
The present invention has simple in structure, is applicable to characteristics such as optical fiber composite insulator.
