A kind of transformer temperature measuring equipment that is applicable to the different pore size thermometer hole
Technical field
The present invention relates to a kind of temperature measuring equipment, be specifically related to a kind of transformer temperature measuring equipment that is applicable to the different pore size thermometer hole.
Background technology
Transformer is carried out real-time temperature survey, can effectively monitor the running status of transformer and line facility, give warning in advance and process the overload running in order to avoid cause unnecessary loss.At present, the transformer that different regions, different manufacturers are produced is reserved not unified standard of thermometer hole specification, existing temperature measuring equipment is that the user reserves the threaded thermometric external member of thermometer hole size custom-made according to its transformer, substation transformer One's name is legion because of Utilities Electric Co.'s administration, producer is many, model is many, capacity does not wait, and it is very high and loaded down with trivial details to customize threaded thermometric external member cost for every kind of transformer.Therefore, how need to think deeply optimal design, so that a kind of transformer temperature measuring equipment can either satisfy the fuel temperature measurement of different manufacturers specifications and models substation transformer, install simultaneously also convenient and swift.
Summary of the invention
Technical matters to be solved by this invention just provides a kind of thousand transformer temperature measuring equipments that are applicable to the different pore size thermometer hole, and it is simple in structure, highly versatile and quick for installation.
For solving the problems of the technologies described above; the present invention adopts following technical scheme: a kind of transformer temperature measuring equipment that is applicable to the different pore size thermometer hole; comprise seal assembly; temperature sensor and protection assembly; described seal assembly comprises top cover; diaphragm seal and securing member; described diaphragm seal is contained in the described top cover; described securing member is used for described top cover is fixedly connected to the outer wall of thermometer hole so that described diaphragm seal and thermometer hole close contact; described protection assembly is fixedly attached on the described top cover; described temperature sensor comprises probe and wire; described probe is arranged in described seal assembly, and described wire is arranged in described protection assembly.
Preferably, described top cover comprises an arcuate flanks, uniform at least two through holes in described side, and described securing member passes described through hole.
Preferably, the position passed of the corresponding described probe of described seal assembly is provided with O-ring seal.
Preferably, at least one projection is set on the described top cover, described protection assembly comprises a umbrella shape screening glass, and described screening glass comprises an inside surface and an outside surface, and described inside surface arranges at least one fastener, and described projection is stuck in the described fastener.
Preferably, described protection assembly also comprises a spring, and described spring is installed in described outside surface center, and described wire passes described spring.
The present invention is connected to the thermometer hole of different pore size by top cover and diaphragm seal are set, be applicable to the transformer thermometric of different manufacturers different size, and highly versatile is quick for installation.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of transformer temperature measuring equipment of the present invention.
Embodiment
As shown in Figure 1; be applicable to the transformer temperature measuring equipment of different pore size thermometer hole for the present invention is a kind of; comprise seal assembly 1; temperature sensor 2 and protection assembly 3; described seal assembly 1 comprises top cover 11; diaphragm seal 12 and securing member 13; described diaphragm seal 12 is contained in the described top cover 11; described securing member 13 is used for described top cover 11 is fixedly connected to the outer wall of thermometer hole so that described diaphragm seal 12 and thermometer hole close contact; described protection assembly 3 is fixedly attached on the described top cover 11; described temperature sensor 2 comprises probe 21 and wire 22; described probe 21 is arranged in described seal assembly 1, and described wire 22 is arranged in described protection assembly 3.
Described top cover 11 comprises an arcuate flanks 14, uniform at least two through holes 141 in described side, and described securing member 13 passes described through hole 141.
The position that described seal assembly 1 corresponding described probe 21 passes is provided with O-ring seal.
At least one projection 15 is set on the described top cover 11; described protection assembly 3 comprises a umbrella shape screening glass 31; described screening glass 31 comprises an inside surface 311 and an outside surface 312, and described inside surface 311 arranges at least one fastener 3111, and described protruding 15 are stuck in the described fastener 3111.
In the present embodiment, two projections 15 and two fasteners 3111 are set, described protruding 15 is spheroid, and described fastener 3111 is offered spherical receiving space.
Described protection assembly 3 has the effect of sunshade and waterproof.
Described protection assembly 3 also comprises a spring 32, and described spring 32 is installed in described outside surface 312 centers, and described wire 22 passes described spring 32.
Described spring 32 can be protected described wire 22, makes described wire 22 that bending than wide-angle can not occur, and prolongs the serviceable life of described temperature sensor 2.
The present invention is connected to the thermometer hole of different pore size by top cover and diaphragm seal are set, be applicable to the transformer thermometric of different manufacturers different size, and highly versatile is quick for installation.
