Description
Technical field:
The utility model relates to high voltage electric equipment field, more precisely isolating switch moving contact position monitoring device in a kind of Cubicle Gas-Insulated Switchgear (GIS).
Background technology:
Cubicle Gas-Insulated Switchgear (GIS) is a kind of high voltage switchgear, is usually applied in 66kV and above high-voltage electric power system, requires that equipment possesses very high reliability.As the main element in Cubicle Gas-Insulated Switchgear, isolating switch act as: when point position, between contact, have satisfactory insulation distance and significantly disconnect mark, can cut off when being such as used in maintenance have electric loop and without electric loop with protection personnel and device security; When co-bit is put, electric current under normal loop condition and the electric current at the appointed time under exceptional condition can be carried.Be in position that half point narrows just may cause failure of insulation or loose contact and accidents caused, to personnel or the grievous injury of equipment precocity if the moving contact of isolating switch is deciliter not in place.
Lead in Cubicle Gas-Insulated Switchgear and be enclosed in metal shell with contact, be difficult to directly estimate it judge or directly measure with device.The position instruction of current each main flow producer product is arranged in mechanism, and can only to indicate point, conjunction state, accurately cannot indicating isolating switch moving contact position, can not accurately indicate for dividing (conjunction) state not in place.
Can indicate that the isolating switch moving contact of Cubicle Gas-Insulated Switchgear divides, co-bit is put and to the whole operational stroke Real-Time Monitoring of isolating switch, necessity very and monitoring system uploading Real-time Monitoring Data just seems.This system carries out analysis Timeliness coverage isolator operation fault by software to measurement result, reminds operating personnel to note, thus can evade the reliability that accident improves Cubicle Gas-Insulated Switchgear by sending alarm signal.
Utility model content:
The utility model object is to provide isolating switch moving contact position monitoring device in a kind of GIS, solves the problem that in GIS, isolating switch moving contact position directly cannot be observed or directly be measured by measuring system.
For reaching above object, the utility model is achieved by the following technical programs:
Isolating switch moving contact position monitoring device in a kind of GIS, comprise isolating switch moving contact and static contact isolation switch, gear train, and universal driving shaft, described universal driving shaft is engaged by gear train with isolating switch moving contact, ensure that being positioned at of operating mechanism rotation is delivered to isolating switch moving contact, and be converted to the stroke of isolating switch moving contact, this universal driving shaft is driven by operating mechanism, described interlock the tip of the axis is connected with the angular displacement sensor measuring universal driving shaft rotational angle, and the output of this angular displacement sensor is connected with monitoring device.
By set of gears group tight mesh between described universal driving shaft and isolating switch moving contact.
Described universal driving shaft is connected with the gear train of multiple stage isolating switch simultaneously.
The telescopic extensions of described isolating switch moving contact is in retraction movable contact block and inserts in fixed contact.
Described universal driving shaft is connected with isolating switch moving contact by turn-screw, and described turn-screw to be inserted in isolating switch moving contact and to be closely cooperated by screw thread with isolating switch moving contact.
Described turn-screw is spacing by the bearing at two ends.
Compared with prior art, in the utility model GIS, isolating switch moving contact position monitoring device at least has following beneficial effect: the utility model connects universal driving shaft by gear train on isolating switch moving contact, at interlock the tip of the axis, angular displacement sensor is set, like this, the change in location of isolating switch moving contact changes the rotation of universal driving shaft into, the rotation of universal driving shaft is gathered by angular displacement sensor, so can monitor the change in location of isolating switch moving contact accurately.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of isolating switch moving contact position monitoring device in a kind of GIS of the utility model;
Fig. 2 is isolation switch contact action transmission schematic diagram in GIS;
In figure: 1, operating mechanism; 2, universal driving shaft; 3, gear train; 4, isolating switch moving contact; 5. angular displacement sensor; 6, telecommunication cable; 7, monitoring device; 8, isolating switch movable contact block; 9, static contact isolation switch; 10, turn-screw.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to shown in Fig. 1, the utility model provides isolating switch moving contact position monitoring device in a kind of GIS, comprises the critical pieces such as three (phase) isolating switch moving contacts 4, operating mechanism 1, universal driving shaft 2, gear train 3, angular displacement sensor 5, a monitoring device 7.Operating mechanism 1 provides operational power to drive universal driving shaft 2 to rotate, universal driving shaft 2 is engaged by gear train 3 with three-phase isolation switch moving contact 4 respectively, thus the displacement making operating mechanism rotate is delivered to isolating switch moving contact, and being converted to the stroke of isolating switch moving contact, the telescopic extensions of isolating switch moving contact is in retraction movable contact block and inserts in fixed contact.Like this, isolating switch turn-screw 10 is driven to rotate by gear drive when universal driving shaft 2 rotates, turn-screw 10 to be inserted in isolating switch moving contact 4 and to be closely cooperated by screw thread with isolating switch moving contact 4, and turn-screw 10 is spacing by the bearing at two ends, and moving contact can move up and down.When turn-screw 10 rotates, isolating switch moving contact 4 does linear telescopic motion under the driving of screw thread.When rotating toward a direction, the moving contact of three-phase isolation switch synchronously stretches out and inserts fixed contact 9, otherwise is synchronously retracted in movable contact block 8.Whole universal driving shaft 2 coordinates closely with three-phase isolation switch moving contact 4 by gear train 3 and turn-screw 10, the equal gapless of all cooperations, the rotation of universal driving shaft 2 drives connecting lever, isolating switch pull bar is synchronized with the movement, from the turned position of universal driving shaft 2 and the telescopic location of isolating switch moving contact 4 synchronously corresponding.
Angular displacement sensor 5 shown in Fig. 1 is arranged on the end of universal driving shaft 2, for measuring the turned position of universal driving shaft 2 in real time, measurement data is digital electric signal, monitoring device 7 is transferred to by telecommunication cable 6, monitoring device 7 obtains desired data result by carrying out process to measurement data, and measurement data to be uploaded by multiple communication modes or exported by monitoring device 7.
By the utility model device, constantly using the foundation of measurement result as executable operations, stop isolating switch moving contact because of deciliter not in place and accidents caused.
Above content is further illustrating of doing the utility model in conjunction with concrete execution mode; can not assert that embodiment of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; all any simple modification of doing according to the utility model Spirit Essence and equivalent structure transformation or modification, all belong to the scope of patent protection that claims that the utility model submits to are determined.
