Abstract
The utility model relates to a rotation angle sensor mounting device for transformer on-load tapping changing switches. The mounting device comprises a mounting frame, a rotation angle sensor and a rubber connecting rod, wherein the rubber connecting rod and a rotation shaft of the rotation angle sensor are in inserted connection and are jointly fixed on the mounting frame; the mounting frame comprises a base and a stand plate; the stand plate is vertically arranged on the base; three uniformly-distributed guide grooves are arranged on the stand plate; fixing devices are arranged in the guide grooves. When the mounting device is in use, the rotation angle sensor is first fixed on the mounting frame with the vertical height adjustable through screws, and then viscous coaxial connection is carried out to a rotating shaft of a driving motor and the rotation shaft of the rotation angle sensor through the elastic rubber connecting rod, which can relieve possible radial torsion caused by coaxial installation errors to the maximum extent and reduce measurement errors. Experiments show that: due to the technical proposal of the utility model, the rotation angle sensor can work stably and not be affected by the radial torsion basically, which can effectively improve measuring accuracy and prolong the life-span of the sensor.
Description
Technical field
The utility model relates to a kind of electrical equipment online monitoring technical field, particularly relates to the auxiliary installation device of a kind of angular sensor when on-load tap changers of transformers is installed.
Background technology
On load tap changer is a movable member unique in the power transformer, also is one of critical component.Rely on load tap changer action accurately and timely, not only can reduce and avoid fluctuating widely of voltage, and can force the distribution load trend, excavating equipment is idle and meritorious exerting oneself, and guarantees the power system security reliability service, increases the flexibility of dispatching of power netwoks.The workmanship of on load tap changer and operation, service technique level are directly connected to the security of operation of on-load tap-changing transformer.The Condition Monitoring Technology of research on load tap changer adapts to the new situations of the national economic development to electric power high-quality, high reliability request to realize rationalization, the standardization, scientific of maintenance of equipment, is of great practical significance.
Mechanical breakdown is the major failure type of on load tap changer.The status monitoring of on load tap changer and failure diagnosis mainly realize by the mechanical features quantity of state that obtains in its operating process, according to available degree, fail safe and the abnormal cause of the variation judgment device of quantity of state, and then propose necessary maintenance measure.
In the on load tap changer handoff procedure if the energy-stored spring performance changes or thermal energy storage process in have phenomenon such as mechanism's jam, must be accompanied by the variation of motor-driven moment, thereby the rotating speed of drive motors is changed.Therefore, the rotary angle signal of monitoring driving motor, but the variation of real-time tracking drive motors verticity are with the mechanical movement state of effective judgement on load tap changer operating mechanism.
Mounting means is most important to the correct use of angular sensor, the useful life that rational mounting means can improve certainty of measurement and transducer.Angular sensor should keep rotation axis and power transmission shaft concentric to install when installing, the rotating shaft of transducer can not bear axially and torsion radially, otherwise damages transducer easily and cause measure error.
But in the middle of the reality, the design of the transmission mechanism of on load tap changer is comparatively compact, and the drive motors rotating shaft end of its operating mechanism exceeds casing and has only several millimeters outward, and the installing space that can utilize is very limited, brings difficulty for the installation of angular sensor.Moreover, be to guarantee power supply and operational reliability, also be simultaneously the basic demand that realizes that non-invasi is measured, electric company does not generally allow to relate to once or the installation or the wiring adjustment of electrical secondary system equipment.Still do not have at present effective especially installation method and can not have mounting auxiliary preferably yet for using for reference.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy for installation, can effectively improve certainty of measurement and prolong the angular sensor erecting device of the on-load tap changers of transformers in transducer useful life.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of angular sensor erecting device of on-load tap changers of transformers, comprise frame and rubber pitman are installed, the rotation axis of rubber bar pitman and angular sensor is pegged graft, and be fixed in jointly on the installation frame, frame is installed comprises base and riser, riser is vertically installed on the base, and riser is provided with three uniform guide grooves, is provided with fixture in the guide groove.
Described fixture is screw or bolt.
When the utility model uses, earlier the rubber pitman from being installed, frame is taken off, again with angular sensor by screw on the adjustable installation frame of vertical height, undertaken by rubber-like rubber pitman between the rotating shaft of drive motors and angular transducer rotation axis then that viscosity is coaxial to be connected, can farthest alleviate the radially torsion that may cause, reduce error in measurement with axle misalignment.Test shows, adopts this technical scheme, but the angular sensor steady operation is not subjected to the radially influence of torsion substantially, can effectively improve certainty of measurement and prolong useful life of transducer.
