Technical Field

The invention relates to the field of GIS isolating switch tools, in particular to a sensor fixing tool for monitoring the on-off state of a GIS isolating switch contact.

Background

GIS room equipment is totally enclosed type combined electrical apparatus, and the switch contact seals in equipment inside, can only pass through the artifical visual inspection of equipment side observation window, but isolator observation window position is higher, the aperture is narrow, the field of vision is dim, is difficult to directly judge contact deciliter position to can produce extremely dazzling arc light at isolator deciliter, rely on conventional artifical pointwise visual inspection method to waste time longer and extremely inconvenient and unsafe, especially on extra-high voltage GIS, extra-high voltage GIS voltage level is high, equipment safety level is high, in case the maloperation appears or the deciliter trouble will bring serious consequence. In order to solve the problem that the actual position of the GIS equipment after switching operation is difficult to detect, and meanwhile, the state data of the contact can be monitored in real time, a sensor for monitoring the on-off state of the contact of the GIS isolating switch needs to be developed, and the functions of real-time remote monitoring, manual judgment and automatic machine judgment double modes can be realized. In the aspect of sensor installation deployment, the cooperation effect of frock needs to be considered emphatically, whether can exert an influence to a body, whether need have a power failure when the installation, whether it is convenient to operate and maintain. The prior art can fix and install the device provided by the device to a certain extent, but has certain defects in the technology:

(1) the sensor and the integrated design of a body, the sensor mounting position is prefabricated when the body is designed, the sensor is mounted on the body when the equipment is assembled once, and the sensor cannot be mounted on the original equipment without the sensor mounting position.

(2) Most of frock and sensor integrated design need disassemble one by one when installation, debugging, fortune dimension, probably can exert an influence to the sealed production of a body.

Disclosure of Invention

The application provides a fixed frock of sensor for monitoring GIS isolator contact deciliter state can realize fixed, whole protection, electromagnetic shield function to GIS isolator contact deciliter state monitoring sensor under the condition that does not change former observation window structural design.

The technical problem solved by the invention can be realized by adopting the following technical scheme:

the utility model provides a GIS isolator contact deciliter state monitoring is with fixed frock of sensor, includes the flange of GIS isolator's remote observation window at least, still includes:

the base is fixed on the axial section of the flange;

the hinge is detachably connected to the base;

one side of the connecting part is detachably connected with the hinge;

the locking portion, this locking portion can dismantle the connection on flange axial cross-section, and locking portion and base symmetry in flange axle center, the locking portion locking is passed through to connecting portion opposite side, makes connecting portion one end and flange laminating.

Further, connecting portion include a positioning cylinder, a connecting cylinder and a connecting ring, connecting cylinder one end is fixed with the end cover, the connecting cylinder other end is outer along fixed with the go-between inner circumference, positioning cylinder one end is fixed with the go-between outer circumference, positioning cylinder, connecting cylinder and go-between are coaxial, the connection can be dismantled with the hinge to one side of the outer circumference of positioning cylinder, the opposite side and the locking portion of the outer circumference of positioning cylinder can be dismantled and be connected, the positioning cylinder other end and flange contact.

Further, the locking portion comprises a support, a pressing plate and a bolt, one end of the support is fixed to the flange, a threaded hole is formed in the center of the other end of the support, a connecting hole is formed in the pressing plate, one end of the bolt penetrates through the connecting hole of the pressing plate and is in threaded connection with the threaded hole, one end of the pressing plate extends out of the support body, and one end of the pressing plate abuts against the axial section of the connecting ring.

Furthermore, the end cover is axially provided with a positioning hole, and a positioning pin is connected with the positioning hole in an internal thread manner.

Furthermore, a sealing strip is embedded on the outer edge of the other end of the positioning cylinder and is in contact with the flange.

Furthermore, the outer periphery of the connecting cylinder is provided with a communication hole, and a flow guide ring is fixed on the outer edge of the communication hole.

The invention has the beneficial effects that: because the flange is provided with the fixed support and the base, the problem that the sensor needs to be additionally arranged on the original structure of the GIS isolating switch is effectively solved, and further the sensor fixing tool does not need to be additionally arranged on the original structure of the GIS isolating switch.

Due to the adoption of the positioning cylinder, the connecting ring and the end cover, the protection of the monitoring sensor is effectively improved, and the damage to the monitoring sensor caused by external force is prevented.

Due to the fact that mechanical locking is adopted, the bolts are screwed to drive the pressing plate to tightly press the connecting ring, the tool can be stably attached to the flange, and the situation that the monitoring sensor has deviation on image collection in the GIS isolating switch due to the fact that locking is not in place is avoided.
