Description
Technical field:
Originally practical to be related to vertical hydrogenerator copper ring lead-out wire temperature monitoring structure.
Background technique:
The threephase AC electric energy that vertical hydropower generator generates when running needs to lead to electricity as carrier to draw copper bar
Net, since draw distance is longer, extraction location is various, multistage draw copper bar using silver soldering connect again close fixation by the way of connect
It connects, and carries out all standing package using insulating materials to guarantee its insulating properties.But it is huge by drawing the electric energy that copper bar is loaded,
When unit long-play, respective location draws the oxidation of copper bar junction, loosens the caused close raising of contact electricity, damage in insulation
Caused short circuit and other reasons can all to draw the raising of copper bar running temperature, and prolonged hot operation can directly puncture
Insulating layer causes adjacent phase fault, then causes three-phase ground short-circuit by short-circuit arc light, unit is caused to damage.Due to heat
Accumulation needs regular hour process, so carrying out real time on-line monitoring to the running temperature for drawing copper bar can effectively prevent
Accident occurs, and guarantees unit safety stable operation.
Summary of the invention:
The purpose of this utility model be disclose a kind of installing and dismounting and updating maintenance is convenient, installation site flexibly, insulation effect
Fruit is good, the accurate vertical hydrogenerator copper ring lead-out wire temperature monitoring structure of temperature monitoring, the technical solution of the utility model
Are as follows: it is integral by upper end clamp plate (1), lower end clamp plate (2), insulated bolt (3), platinum resistance thermometer sensor, (4) group, it uses upper end clamp plate (1)
Platinum resistance thermometer sensor, (4) is fixed on to the upper surface for drawing copper bar (5), then touch extraction copper from bottom to top using lower end clamp plate (2)
The lower surface for arranging (5) reuses insulated bolt (3) for upper end clamp plate (1) and lower end clamp plate (2) fixation is closed, forms entirety, on
End clamp plate (1) and connecting closing for lower end clamp plate (2) are that have gap connection.The upper end clamp plate (1) is spill cuboid knot
Structure, isolation material, the design of left and right edges two sides have the through-hole (9) with insulated bolt (3) cooperation, the design of lower inside center
The first groove (8) for having and drawing copper bar (5) cooperation, the first groove (8) are through groove, and top design has resistance card slot
(10) to fixed platinum resistance thermometer sensor, (4), resistance card slot (10) is non-through rectangle card slot, and side design has for resistance lead
(6) cable aperture (7) drawn；The lower end clamp plate (2) is spill rectangular parallelepiped structure, and isolation material, the left and right sides, which is designed, to be had
With the screw hole (12) of insulated bolt (3) cooperation, the design of inner upper center has the second groove with extraction copper bar (5) cooperation
(11), the second groove (11) is through groove；Platinum resistance thermometer sensor, (4) the side design has resistance lead (6) to draw temperature
Signal.
Technical effect:
1. the utility model compact structure, light-weight, it can be arranged in draw in copper bar laying path according to the actual situation and appoint
On what higher position of risk, and it is easy for installation, it does not need to weld, only by the way that installation can be completed fixation is closed；
2. the utility model stable structure, platinum resistance thermometer sensor, is embedded on the inside of end clamp plate in card slot, is hardly damaged, and can be only
Only the upper surface of copper bar is drawn in fitting, can accurately transmit temperature signal steadily in the long term；
3. when needs overhaul replacement or reselect laying position, it is only necessary to the conjunction for unlocking insulating nut, it can be complete
At disassembly and replacement, structure is simple, is hardly damaged.
