Description
Technical field
The utility model relates to disconnecting switch technical field, has moving contact position detecting function more particularly, to a kind of
Disconnecting switch.
Background technique
BF12 type double-fracture horizontal rotation type disconnecting link is widely used in high voltage direct current transmission project, and dynamic/static contact contacts machine
Structure is special, and making process is divided into two steps, and the horizontal rotation of first step conducting rod moves to moving contact in static contact U-type groove, and second
Step conducting rod is rotated around own axes makes moving contact bow strip move to the final static contact fingertip clamping moving contact of vertical direction.Directly
The I/O Sign Board for flowing disconnecting link actuating strut, can only indicate the positional relationship of moving contact and static contact, cannot directly indicate that static contact touches
Refer to and clamp moving contact, the position instruction of this Sign Board cannot function as the foundation of disconnecting link in-place closing.And due to bow strip length
Shorter, whether the more difficult determining direct current switch fixed contact fingertip of field position scrutineer clamps moving contact, in converter station O&M process
Middle there is direct current moving contact of disconnecting link bow strip and static contact fingertip does not reach position and damages the event of direct current disconnecting link, in addition to straight
Economic loss is connect, direct current unplanned outage event is also caused.
Utility model content
The purpose of this utility model is intended to overcome the shortcomings of the prior art, provides a kind of effectively detection moving contact position
It sets, improves the disconnecting switch of power grid security.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:
A kind of disconnecting switch having moving contact position detecting function, including static contact outline border, are rotatably dispose in static contact
In outline border, the moving contact with two bow strips, two be symmetrically disposed on static contact outline border, the fingertips with bow strip cooperation, setting
The cushion contacted on static contact outline border with moving contact, a spring and intelligent pressure sensor；The intelligent pressure sensor peace
Loaded on static contact outline border, its measurement end and the wherein motion end of a fingertip it is corresponding and in close proximity to one another；One end of the spring
It is connect with the measurement end of intelligent pressure sensor, the other end is connect with the motion end of the fingertip of the neighbouring intelligent pressure sensor.
It preferably, further include remote terminal equipment.
Preferably, the intelligent pressure sensor is installed on static contact outline border by screw.
Preferably, the spring is connected by the measurement end of clamping structure and intelligent pressure sensor.
Preferably, the spring is connected by the motion end of clamping structure and fingertip.
Compared with prior art, the utility model has the advantages that
The utility model can receive the pressure value of intelligent pressure sensor detection by remote terminal equipment, then judge
Whether bow strip position contacts well out, to reduce electric network fault, improves the safety of operation of power networks.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

The structure and working method of utility model will be described on the basis of attached drawing by many Directional words, but should be incited somebody to action
The Word Understandings such as "front", "rear", "left", "right", "upper", "lower" are not construed as word of limitation for convenience of term.
Have the disconnecting switch of moving contact position detecting function, including static contact outline border 4 shown in Fig. 1, is rotatably dispose in quiet
In contact outline border 4, the moving contact 3 with two bow strips 2, two be symmetrically disposed on static contact outline border 4, cooperate with bow strip 2
The cushion 5 contacted on static contact outline border 4 with moving contact 3, a spring and intelligent pressure sensor 7 is arranged in fingertip 1；Its feature
Be: the intelligent pressure sensor 7 is installed on static contact outline border 4, its measurement end is opposite with the wherein motion end of a fingertip 1
It answers and in close proximity to one another；One end of the spring is connect with the measurement end of intelligent pressure sensor 7, and the other end and neighbouring this are intelligently pressed
The motion end of the fingertip 1 of force snesor 7 connects.
It further includes remote terminal equipment 9, and mobile phone, tablet computer or computer can be used in remote terminal equipment.
The PTG500 Series Pressure that Guang Yi Electron equipment Co., Ltd, Zhongshan city can be used in the intelligent pressure sensor passes
Sensor；The intelligent pressure sensor 7 is installed on static contact outline border 4 by screw, it is clear that also can be used bonding etc. modes into
Row connection.The spring 8 is connect by clamping structure with the measurement end of intelligent pressure sensor 7, it is clear that also can be used be bonded or
The modes such as riveting are attached.The spring 8 is connect by clamping structure with the motion end of fingertip 1, it is clear that bonding also can be used
Or the modes such as riveting are attached.
Intelligent pressure sensor takes electricity without battery by the temperature difference, and by radio transmitted pressure information, has non-maintaining
