Abstract
The utility model relates to a measurement positioning apparatus for simulating a temperature rise of a structural part in a transformer oil tank and belongs to the technical field of electromagnetic measurement devices. The technical scheme is that the measurement positioning apparatus for simulating the temperature rise of the structural part includes a coil (1), the oil tank (2), a positioning support (3) and the structural part (4), wherein the coil (1) is fixedly arranged on an upper portion of the positioning support (3), the coil (1) and the positioning support (3) are mounted in the oil tank (2) together, and the structural part (4) is disposed on a side surface of the positioning support (3). The beneficial effects of the measurement positioning apparatus are that a temperature rise of the coil is reduced, so that the coil working under excitation of heavy current for a long period of time is not too hot to damage an insulation structure; a work condition in the transformer oil tank is simulated, so that a temperature rise of the structural part, measured under the condition, is better referable and instructive; and the measured structural part is accurately positioned, so that measurement errors because of inaccurate structural-part positioning are avoided.
Description
Technical field
The utility model relates to the measurement and positioning device of a kind of analogue transformer fuel tank internal structural member temperature rise, belongs to the electromagnetic measurement equipment technical field.
Background technology
At present, due to not allowing of the complicacy of power transformer product, not easy to assemble and working condition, the temperature measurement of oil tank of transformer inner structural members is not easy to realize.Member temperature rise generally can only be measured in air, and does not have the temperature measurement result under oily cycling condition not to be used for preferably instructing production practices, and due to the increasing exciting current of needs, the heat radiation of test coil also becomes a problem.
The utility model content
The utility model purpose is to provide the measurement and positioning device of a kind of analogue transformer fuel tank internal structural member temperature rise; oil environment and accurate locating formation are provided; both reduced coil temperature rise; thereby protected the coil insulation structure; make again structural member temperature measurement result that better directiveness is arranged, solve the problems referred to above that exist in background technology.
The technical solution of the utility model is: the measurement and positioning device of a kind of analogue transformer fuel tank internal structural member temperature rise, comprise coil, fuel tank, locating support and structural member, described coil is fixedly installed on the top of locating support, both be arranged on together the inside of fuel tank, described structural member is arranged on the side of locating support.
One side of described locating support is provided with rectangular locating slot, and structural member is arranged in locating slot.
The bottom of described locating support is provided with more than one rectangular slot and circular hole.
The material of described fuel tank and locating support is the insulation nonferromagnetic material.
Described structural member has three kinds, is respectively structural member one, structural member two and structural member three.
The beneficial effects of the utility model are: reduced the temperature rise of coil, made the coil because working long hours under large current excitation be unlikely to the overheated insulation system that damages.Simulated the condition of work in oil tank of transformer, the structural member temperature rise of measuring with this understanding has better reference and directiveness.Accurately located the structural member that needs measurement, avoided because of the inaccurate measuring error of bringing in structural member location.
