Description
Technical field
It expands with heat and contract with cold the present invention relates to a kind of power system device and deforms alarm device, especially substation's gas-insulated is opened
The deformation monitoring alarm device for closing integrated equipment piping, belongs to substation equipment maintenance and repair site technology field.
Background technique
The full name of GIS is Cubicle Gas-Insulated Switchgear.It is mutual by breaker, bus, disconnecting switch, voltage
High voltage distribution installation made of the combination of the elements such as sensor, current transformer, arrester, casing, earthing, GIS is using exhausted
Edge performance and excellent sulfur hexafluoride (SF6) gas of arc extinction performance are as insulation and arc-extinguishing medium, and by all High-Voltage Electrical Appliances
Component seal is in grounded metal cylinder.Therefore compared with ordinary distribution device, with occupied area, small, element all seals GIS
Not by environmental disturbances, operational reliability is high, operation is convenient, the time between overhauls(TBO) is long, maintenance workload is small, installation is rapid, operating cost
The advantages that low, without electromagnetic interference.GIS is since nineteen sixty-eight develops, and development is very fast, and GIS technology has become contemporary high-voltage electricity
The mainstream of device.
However, be easy to causeing pipe bus each in various load in Cubicle Gas-Insulated Switchgear operational process
Non-uniform deformation is generated between part, or even is destroyed, to easily cause the leakage of sulfur hexafluoride gas.GIS combination electric appliance is set
Standby piping due to summer in winter the big temperature difference and generation temperature deformation, along with reasons such as product quality and mounting process,
There is biggish security risks for weak locations at bus flange docking etc..SF6 gas is set once a leak occurs, will directly threaten
Standby safe operation causes significant damage to the safety of electrical equipment, personnel and environment.It sometimes has to carry out power-off dimension
It repairs, brings about great losses to industrial and agricultural production.In addition, also certain harm can be brought to the person and environment.Existing China 220kV with
Lower substation is mostly unattended, and most power supply companies do not cause enough attention, sliding branch to GIS piping deformation amount inspection
Seat deflection and more difficult quantitative observation, so being not easy to realize to the control of GIS piping deformation amount.
Summary of the invention
To overcome problems of the prior art, the present invention provides a kind of GIS piping deformation monitoring alarm devices.
The technical scheme adopted by the invention to solve the technical problem is that: this kind of GIS piping deformation monitoring alarm device, packet
Sliding support, indicating section and alarm part are included, sliding support is equipped with the sliding block that can be slided along sliding support, sliding block and pipeline
It contacts, the displacement of pipeline and sliding block can be shown in indicating section, indicating section and alarm part Electricity Federation.
Further, the indicating section includes sliding slot, pointer, graduated scale and metal contact, and the sliding slot is straight line
Sliding slot, pointer can slide in sliding slot, and pointer tip indicates on graduated scale, and the adjustable metal touching in position is arranged in sliding slot both ends
Head, sliding block connect with pointer and drive pointer and sliding block synchronization action.
Further, the pointer can move in sliding slot and can contact the metal contact at both ends, and pointer is metal material.
Further, the alarm part includes warning indicator light, and warning indicator light is connect with metal contact by conducting wire.
Further, when pointer touches metal contact, alarm circuit is connected, warning indicator light alarm.
Further, the displacement of the pointer is identical as the displacement of sliding block and pipeline.
To sum up, the advantageous effects of the above technical solutions of the present invention are as follows:
The apparatus structure is simple, small in size, saves space.When the deformation quantity of pipeline reaches warning point, device alarm, and
And can intuitively observe the displacement of GIS piping sliding support, to judge the deflection of the segment pipe.
(1) structure is simple, can effectively implement, applied widely.Dimensional fits are adjusted according to different types of pipeline, it can be with
It is applicable at various pipes sliding support, structure is relatively simple with circuit for alarming, in the case where guaranteeing technique, is less prone to
Failure, such as sliding slot obstruction, circuit abnormality, indicating section can individually be taken if instruction device or alarm device are when something goes wrong
Under, it is convenient to overhaul.
(2) shift value of sliding support sliding block can be intuitively read, thus judge that can sliding block work normally at this, it should
Whether normal locate thermal expansion of pipeline, if need to apply the measures such as heat preservation or structure optimization.There is warning what displacement reached setting
When point can timely closed circuit, effective alarm prevents over-large displacement, can be also integrated into alarm device by integrated circuit
Monitoring area facilitates the monitoring in unattended situation to substation.
Detailed description of the invention

Specific embodiment
Feature and principle of the invention are described in detail below in conjunction with attached drawing, illustrated embodiment is only used for explaining this hair
It is bright, not limited the scope of protection of the present invention with this.
Structural schematic diagram of the invention is as shown in Figure 1, it includes sliding support 1, indicating section 2, alarm part 3.Instruction
Graduated scale 11 is carved in 2 upper surface of part, as shown in fig. 1.Pointer 5 should refer to " 0 " scale when initially installing, and length should not be small
When the total length of sliding slot 6 reaches alarm value to ensure to be displaced, pointer 5 can be contacted with metal contact 7.In sliding support 1
Sliding block 4 is connected with pointer 5 by the aperture 10 reserved on sliding block 4.Pipeline is deformed due to expanding with heat and contract with cold, and moves sliding block 4
It is dynamic, so that pointer 5 be driven to move along the axial direction of sliding slot 6, by the variation of record scale can quantitatively when obtaining this
Between section sliding support inner slide 4 herein misalignment, to obtain the deformation of pipeline.Indicating section 2 should be fixed on cunning
On the steelframe of dynamic 4 moving direction of support sliding block, the two distance view field condition is determined, guarantees that sliding block 4 can drive pointer 5 in sliding slot
Displacement is generated in 6 and is mutually all principle with sliding block 4 itself displacement.
As shown in figure 3, pointer is metal material, the metal contact 7 of pointer 5 and 2 end of indicating section by conducting wire 9 with
Warning indicator light 8 is connected, and when the displacement of pointer 5 is gradually increased until when being in contact with metal contact 7, alarm circuit is connect
Logical, warning indicator light 8 is alarmed, and warning indicator light 8 may be provided at the observable position of on-site supervision or be integrated into distal end and supervises
Control is indoor, to facilitate the monitoring of unattended operation transformer station.
Metal contact 7 can also 6 movement along the chute.After setting the admissible maximum displacement numerical value of sliding block 4, metal is adjusted
The initial distance of contact 7 and pointer 5 is maximum displacement numerical value, to achieve the purpose that adjust alarm value size.
