Description
Technical field
This utility model relates to technical field of temperature measurement, particularly refers to a kind of based on sound table device be arranged at busbar
On arrangement of temperature sensor.
Background technology
The equipment that power plant, the high-tension switch cabinet of transformer station, busbar joint, outdoor chopper switch, cable interface etc. are important,
In During Process of Long-term Operation, the position such as the contact of switch and bus connection because of aging or contact resistance is excessive and generates heat, these
The temperature in hot spot is not monitored, and the accident that thus ultimately results in occurs.In recent years, there is a lot of opening in power plant and transformer station
Closing overheat accident, cause fire and large-area power outage, solving switch problems of excessive heat is to stop the pass that this type of accident occurs
Key, it is achieved on-line temperature monitoring is to ensure that the important means of high pressure equipment safe operation.Traditional thermometric mode insulating properties,
Various problem is there is on mounting means, reliability stability and implementation cost.
Wireless and passive temperature online monitoring system is a kind of brand-new thermometry based on surface acoustic wave (SAW).This prison
Examining system is mainly made up of temperature sensor, harvester, reception antenna, monitoring host computer.Existing distribution switchgear cabinet temperature monitoring,
Bus bar position is that sensor installs one of modal position, sensor construction many employings prong type on busbar, first will during installation
Busbar bolt is unscrewed, again by screw tightening after insertion sensor.This mounting means exists because long-term micro-vibration of switch cubicle is made
Become busbar screw or sensor to get loose the hidden danger dropped, and conventional busbar sensor many employings plastic shell be as protecting,
The occasion (higher than 150 degree Celsius) that temperature requirement is higher then cannot be met use requirement.
Utility model content
The purpose of this utility model is to solve the problems referred to above and proposes a kind of busbar temperature transducer structure, and it can solve
Certainly sensor is owing to being chronically in vibration environment the defect easily coming off and cannot being used in the higher occasion of temperature.
To achieve these goals, the technical scheme that this utility model is taked is as follows:
The utility model proposes a kind of busbar temperature transducer structure, including copper fixture and PCBA assembly, described PCBA
Assembly is welded together with described copper fixture by print solder, and described copper fixture is a laminated structure in cuboid,
Described copper fixture includes that left-half and right half part, the left-half of described copper fixture are provided with and runs through described copper and fix
The manhole of part, described PCBA assembly is located on the right half part of copper fixture, described PCBA assembly be externally provided with protection
Shell, within described PCBA assembly is placed in protection shell.
Further, described protection shell is formed by PCBA assembly injection epoxy resin.
The beneficial effects of the utility model:
1., compared with traditional sensor construction form using prong type, this utility model is by setting on copper fixture
Put a manhole, during installation, only manhole need to be enclosed within busbar lead screw, then can realize passing by fastening nut
Fixing of sensor, simple in construction, fixing reliable；
2. this utility model PCBA assembly uses injection epoxy resin sealing to protect, epoxy resin heat-resist,
Make sensor can be operated in the occasion that temperature is higher, without affecting its service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of busbar temperature transducer structure.
Wherein, 1-copper fixture, 2-PCBA assembly, 3-protects shell, 11-manhole.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Based on the enforcement in this utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into
The scope of this utility model protection.
As background technology is introduced, traditional sensor construction many employings prong type being used on busbar, after installation
Exist because long-term micro-vibration of switch cubicle causes busbar screw or sensor to get loose the hidden danger dropped, to this end, this utility model carries
Go out a kind of busbar temperature transducer structure, including copper fixture 1 and PCBA assembly 2, described PCBA assembly 2 by print solder with
Described copper fixture 1 welds together, and described copper fixture 1 is a laminated structure in cuboid, and described copper fixture 1 includes
Left-half and right half part, the left-half of described copper fixture 1 is provided with the manhole running through described copper fixture 1
11, described PCBA assembly 2 is located on the right half part of copper fixture 1, and shell 3, institute are protected in being externally provided with of described PCBA assembly 2
State PCBA assembly 2 be placed in protection shell 3 within.
As can be seen here, compared with traditional sensor construction form using prong type, this utility model is by solid at copper
One manhole 11 is set in locking member 1, during installation, only manhole 11 need to be enclosed within busbar lead screw, then by tightening
Nut can realize the fixing of sensor, simple in construction, fixes reliable.
In addition to the above, in order to solve traditional sensor being used on busbar, can not to be used in higher temperature (high
In 150 degree Celsius) under the conditions of defect, the protection of PCBA assembly 2 is used injection epoxy resin sealing to carry out by this utility model
Protection, injection epoxy resin to form protection shell 3, heat-resist due to, epoxy resin so that sensor can be operated in
The occasion that temperature is higher, without affecting its service life.
Last it should be noted that, above example is only in order to illustrate the technical solution of the utility model, rather than to this reality
With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general
Logical it will be appreciated by the skilled person that the technical solution of the utility model can be modified or equivalent, without deviating from this
The spirit and scope of utility model technical scheme.
