Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description herein is merely for purposes of illustration and explanation and is not intended to limit the embodiments of the present invention.
In the embodiments of the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, top, and bottom" is generally used with respect to the orientation shown in the drawings or the positional relationship between the components in the vertical, or gravitational direction.
In addition, if there is a description in the embodiments of the present invention referring to "first", "second", etc., the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments can be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or can not be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.
Fig. 1 is a schematic structural diagram of an intelligent end screen device integrated with an internal sensor according to an embodiment of the present invention. In fig. 1, the smart end screen device may include a bushing housing 01, a humidity sensor 02, and an online monitoring module 03.
Specifically, in fig. 1, the interior cavity of bushing housing 01 may be used to house bushing end screen grounding guide 04 of the high voltage bushing. The cannula housing 01 may be provided with at least one through hole. The humidity sensor 02 may be disposed between the casing 01 and the casing end screen grounding guide 04, and is configured to obtain humidity of a cavity between the casing 01 and the casing end screen grounding guide 04 in real time. The online monitoring module 03 can be connected with the humidity sensor 02 through the through hole, and is used for determining the real-time grounding condition of the high-voltage bushing in real time according to the feedback information of the humidity sensor 02.
In an embodiment of the present invention, it is considered that different online monitoring modules 03 can be connected to different humidity sensors 02 in a matching manner. Accordingly, an aircraft plug 06 can be arranged in a through-opening in the bushing housing 01. One end of the aviation plug 06 can be connected with the humidity sensor 02, and the other end can be connected with the online monitoring module 03. Therefore, the equipment can be conveniently plugged and pulled out.
In an embodiment of the present invention, since the bushing shell 01 and the end shield terminal base 07 of the high-voltage bushing are both rigid structures (the end shield terminal base 07 and the bushing end shield grounding guide rod 04 are the end shield insulation sleeve 05 therebetween), a gap is easily formed between them when installing. These gaps can easily lead to the ingress of moisture during operation of the bushing, thereby resulting in a poor grounding of the bushing. Thus, in fig. 1, the bottom end of the bushing housing 01 near the end shield terminal base 07 may be provided with a sealing ring 08.
Further, it is considered that the grounding condition of the high voltage bushing can be determined in real time although only the humidity is monitored. However, under some special conditions (such as abnormal operation of the grounding guide rod of the high-voltage bushing), it is difficult to detect the fault by monitoring the humidity only. Therefore, in an embodiment of the present invention, the smart end screen device may further include a temperature sensor 02 a. Similar to the humidity sensor 02, a temperature sensor 02a may also be disposed between the casing housing 01 and the casing end screen grounding guide 04 for acquiring the temperature of the cavity between the casing housing 01 and the casing end screen grounding guide 04 in real time. Further, the temperature sensor 02a and the humidity sensor 02 may be integrated as a temperature and humidity sensor for the convenience of device management and design.
On the other hand, the utility model also provides a high-voltage bushing, this high-voltage bushing can include the high-voltage bushing body and as aforesaid arbitrary intelligent end screen device.
Through the technical scheme, the utility model provides an integrated internal sensor's high-tension bushing and intelligence end screen device thereof sets up humidity transducer through the inside at the sleeve pipe shell to set up the on-line monitoring module and handle this humidity transducer's feedback information, thereby realized the real-time supervision of high-tension bushing's ground connection condition.
The above describes in detail optional embodiments of the present invention with reference to the accompanying drawings, however, the embodiments of the present invention are not limited to the details of the above embodiments, and the technical concept of the embodiments of the present invention can be within the scope of the present invention, and can be modified in a variety of ways, and these simple modifications all belong to the protection scope of the embodiments of the present invention.
It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the embodiments of the present invention do not separately describe various possible combinations.
In addition, various different embodiments of the present invention can be combined arbitrarily, and the embodiments of the present invention should be considered as disclosed in the embodiments of the present invention as long as the embodiments do not depart from the spirit of the embodiments of the present invention.
