Abstract
A composite material insulator capable of immediately monitoring internal strain and temperature variation comprises a mandrel and an optical fiber sensor. The mandrel is fixed onto an axis of an umbrella skirt, the optical fiber sensor is fixed onto the mandrel, a bulb fitting is crimped on the mandrel, a groove parallel to an axis of the mandrel is disposed on the surface of the mandrel, the optical fiber sensor is arranged in the groove, optical fiber through holes are disposed on the bulb fitting, and tail fibers of the optical fiber sensor penetrate out from the optical fiber through holes. In the composite material insulator capable of immediately monitoring internal strain and temperature variation, the optical fiber sensor is embedded onto the mandrel, once stress change or temperature of the mandrel is abnormal, monitors can find the abnormal stress change or temperature in time, and if the abnormal stress change or temperature potentially causes major accidents, workers can take measures in time so as to avoid accidents. The optical fiber sensor is embedded linearly, thereby reducing utilization amount of optical fibers, reducing production cost and avoiding damage of the optical fibers during usage.
Description
Technical field
The utility model relates to a kind of composite insulator device of ultra-high-tension power transmission line, is specially a kind of composite material insulator that can monitor high voltage composite insulators internal strain amount and variations in temperature at any time.
Background technology
The insulator arrangement that has adopted at present composite material to make in ultra-high-tension power transmission line in a large number, this composite material insulator is made of silicon rubber full skirt and epoxy resin composite material plug usually.Bear whole load by plug during use.Because plug also bears the stress that other machinery, electromagnetism, variations in temperature etc. produce in bearing load, these can cause that all the plug internal stress changes, and cause plug impaired, and severe patient can make mandrel fracture, causes a serious accident.Though this variation is long-term stressed formation, because these variations are formed at inside, therefore its outside demonstration and not obvious, causes very big difficulty to daily monitoring.At the problems referred to above, prior art has proposed to adopt the mode of pre-buried Fibre Optical Sensor, monitors composite material electric(al) insulator STRESS VARIATION situation in real time.As Chinese patent 02120069.6 disclosed a kind of " the composite material electric(al) insulator that comprises combined fibre-optical sensor ", its method that adopts is that Fibre Optical Sensor is wrapped on the plug, and the daily STRESS VARIATION of plug is monitored.This canoe optical fiber consumption is big, and the fiber lengths increase is easier to be impaired, and difficulty of processing also increases.
Summary of the invention
The deficiency that the utility model exists at above-mentioned prior art, but the composite material insulator of a kind of at-once monitor internal strain amount and variations in temperature designed.
But the composite material insulator of a kind of at-once monitor internal strain amount of the present utility model and variations in temperature, comprise and be fixed on the plug on the full skirt axis and be fixed on Fibre Optical Sensor on the plug, on plug, be crimped with the bulb gold utensil, be shaped on groove with the mandrel axis line parallel at mandrel surface, in groove, be provided with Fibre Optical Sensor, the optical fiber through hole is arranged on the bulb gold utensil, and the tail optical fiber of described Fibre Optical Sensor is passed by the optical fiber through hole.
But the composite material insulator of described a kind of at-once monitor internal strain amount and variations in temperature, wherein the bending radius of optical fiber through hole is greater than the fibre-optical bending permissible value.
But the composite material insulator of a kind of at-once monitor internal strain amount of the present utility model and variations in temperature; Fibre Optical Sensor is imbedded on the plug; in case the unusual or temperature anomaly of STRESS VARIATION appears in plug; the monitor staff can in time find; if expressing possibility, anomaly causes that major accident takes place; the staff can in time take measures, and avoids accident to take place.Adopt orthoscopic to bury underground Fibre Optical Sensor, reduced the optical fiber consumption, reduced production cost, avoided optical fiber in use impaired.

Embodiment
But elaborate below in conjunction with the composite material insulator of accompanying drawing to a kind of at-once monitor internal strain amount of the present utility model and variations in temperature.
Shown in Fig. 1-2, composite material insulator is made up of plug 2 and the insulator full skirt 1 that is socketed in the plug outside, be crimped with bulb gold utensil 4 at the plug two ends, carve the square groove 9 of 1 * 1mm with milling machine along the mandrel surface direction that parallels to the axis, optical fiber is embedded in the groove 9, uses the epoxide-resin glue filling groove then.Place the interior optical fiber of groove to be provided with the induction grating of some points, be used to respond to the extraneous concurrent bright dipping induced signal that changes.
Shown in Figure 3, the lead-out wire of optical fiber is tail optical fiber 5 from the bulb gold utensil optical fiber through hole 6 passes, and ferrule 7 is arranged on tail optical fiber, avoids impaired in order to protection optical fiber.The bending radius of optical fiber through hole 6 should be asked permissible value greater than fibre-optical bending.To guarantee the normal transmission of light signal.
Among Fig. 4, be fixed with bulb gold utensil 4 by the crimping mode, adopt fluid sealant 8 to seal fully in the optical fiber exit position at plug 2 two ends.
During use, to be fixed with the composite material insulator of Fibre Optical Sensor by normally laying, at optical fiber buttock line termination optical signal receiver and photoelectric signal converter, said apparatus is connected with computer, can reacts the real-time embedded stress of this composite material insulator, variations in temperature situation on computers.Because the insulation situation of change of composite insulator is often relevant with heating.Partial discharge, the dielectric loss that causes when leakage current flows through megohmite insulant or resistance loss all can make the temperature of minor insulation raise.Can find the local damage and the discharge defect of composite insulator according to the heating phenomenon.
