The optical-fiber grating temperature sensor is positioned in a mounting groove of the lower mounting base fixed in advance and is covered by the upper cover plate, and the upper cover plate and the lower mounting base are connected by screws in threaded holes of the upper cover plate so that the optical-fiber grating temperature sensor probe is fixed by compression. The device has the advantages of simple structure, convenient installation and fastened fixation.
Description
Technical field
The invention belongs to the frock clamp field of enclosure-type power distribution cabinet, be specifically related to a kind of stationary installation of enclosure-type power distribution cabinet internal optical fiber temperature probe.
Background technology
In enclosure-type high-low voltage electric power distribution cabinet apparatus field; Because the requirement of the working environment of enclosure-type power distribution cabinet; Therefore the working environment of power distribution cabinet is airtight, along with various electronic devices and components and cable aging, important electrical equipment and the contact point between the cable can cause contact resistance excessive and generate heat because of dust, loosening, oxidation; And abnormal heating position can cause various potential safety hazards; But because the sealing requirements of enclosure-type power distribution cabinet, the way that the person's of patrolling and examining routine is patrolled and examined is difficult to observe inner working condition, and because conventional inside temperature measuring equipment all is contactless temperature measuring device; And be easy to receive the interference of environmental factors such as various electromagnetism or power distribution cabinet internal temperature height; Therefore it is inaccurate thermometric to occur, the shortcoming of job insecurity, so fiber-optical grating temperature sensor begins constantly to be applied in widely the thermometric field of enclosure-type power distribution cabinet.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the purpose of this invention is to provide a kind of stationary installation of enclosure-type power distribution cabinet internal optical fiber temperature probe, have simple in structure, connection reliable characteristics.
To achieve these goals; The technical scheme that the present invention adopts is: a kind of stationary installation of enclosure-type power distribution cabinet internal optical fiber temperature probe; Include the upper cover plate that links to each other with following mounting base, be fixed with fastening fiber-optical grating temperature sensor probe on the mounting base down.
Described mounting base down is provided with three mounting grooves, is provided with the clamp groove in the mounting groove, and both sides are provided with the docking recess with the upper cover plate butt joint.
Described upper cover plate is provided with and the corresponding mounting groove of following mounting base.
Described mounting base down and upper cover plate are through the screw retention in four middle threaded holes.
Described mounting base down and upper cover plate inside surface are provided with lines.
The invention has the beneficial effects as follows:
Because the present invention is being provided with three mounting grooves that the fixed fiber grating temperature sensor is popped one's head in the mounting base down; Following mounting base and the design of upper cover plate inside surface lines; Friction force when having increased displacement; Better limited moving of fiber-optical grating temperature sensor probe, made the fiber-optical grating temperature sensor probe fixing more solid and reliable.
Description of drawings
Accompanying drawing 1 is apparatus of the present invention structural representation.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and principle of work are done further explain.
Referring to accompanying drawing, a kind of stationary installation of enclosure-type power distribution cabinet internal optical fiber temperature probe includes the upper cover plate 5 that links to each other with following mounting base 3, is being fixed with fastening fiber-optical grating temperature sensor probe 1 on the mounting base 3 down.
Described mounting base 3 down is provided with three mounting grooves 2, is provided with clamp groove 8 in the mounting groove 2, and both sides are provided with the docking recess 9 with upper cover plate 5 butt joints.
Described upper cover plate 5 is provided with and following mounting base 3 corresponding mounting grooves.
Described mounting base 3 down passes through the interior screw retention of four middle threaded holes with upper cover plate 5.
Described mounting base 3 down is provided with lines with upper cover plate 5 inside surfaces.
Fiber-optical grating temperature sensor probe 1 can be selected the installation site according to the needs of diverse location, makes the installation site become flexible and changeable, adapts to the needs of various installation occasions; 8 of clamp grooves allow optical fiber to pass through, and have blocked moving down of fiber-optical grating temperature sensor probe 1, and flexibly simple design has well limited fiber-optical grating temperature sensor probe 1 and has been subjected to displacement; Docking recess 9 has the effect of two aspects: the firstth, and spacing fixed cover plate 5 makes things convenient for the bossing 4 of upper cover plate 5 to put into docking recess 9, has limited upper cover plate generation transversal displacement in the horizontal; The secondth, better the fixed fiber grating temperature sensor is popped one's head in; Design through docking recess 9 surpluses; Constantly mounting base extruding downwards when upper cover plate is installed, what better 1, three mounting groove of fixed fiber grating temperature sensor probe bossing that is upper cover plate left enough is used for the surplus that extrusion temperature pops one's head in; Design in this way can well be popped one's head in by the fixed fiber grating temperature sensor; Can make the fiber-optical grating temperature sensor probe can in stationary installation, not be subjected to displacement activity, be aided with mounting base 3 and the design of upper cover plate 5 inside surface lines, the friction force when having increased displacement down again; Better limited moving of fiber-optical grating temperature sensor probe 1, made fiber-optical grating temperature sensor probe 1 fixing more solid and reliable.
Described mounting base 3 down will be installed to the temperature survey point of enclosure-type power distribution cabinet, is screwed the temperature survey point that fiber-optical grating temperature sensor probe 1 will be installed through threaded hole 10 is installed.
Mounting means of the present invention:
Fiber-optical grating temperature sensor probe is installed in down in the mounting groove of mounting base 32, three mounting grooves 3 and can selects the most suitable installation site according to concrete needs; Optical fiber is put into clamp groove 8, prevents that temp probe from moving down, spacing fiber-optical grating temperature sensor probe 1; Cover upper cover plate 5; The bossing 4 of upper cover plate will be put into down in the docking recess of mounting base 3 both sides, puts well after the upper cover plate 5, and the preprepared threaded fastener screw is fit into up and down in the connection screw thread hole; Firmly screw, through the fixing fastening temperature sensor probe of extruding of cover plate up and down.
The above; Only be the embodiment of the inventive method; Be not that the present invention is done any restriction, every technical scheme replaces all still belonging in the protection domain of technological system of the present invention to any simple modification that above embodiment did, the variation of structure according to the present invention.
