The real-time water level monitoring device comprises a transformer, more than two water level indicating lamps and more than two liquid level switches, wherein one water level indicating lamp and one liquid level switch are connected in series with each other to form a liquid level displaying branch; the liquid level switches are positioned at different heights; more than two liquid level displaying branches are connected in parallel to the two output ends of the transformer. The real-time water level monitoring device can monitor a water level in the cable tunnel in real time; a worker can observe the water level without opening a cable tunnel cover plate; the labor intensity is reduced, and the working efficiency is improved.
Description
Technical field
The utility model relates to Level monitor technical field, relates in particular to a kind of cable tunnel water level real-time monitoring device.
Background technology
Though the unlikely cable sheath insulation damages that causes at short notice of transformer station's cable tunnel ponding, ponding may flow to switch cubicle bottom by cable tunnel, inside switch cabinet is made moist, serious threat switch cubicle security of operation.The operating standard > > of < < Hebei Electric Power Corporation explicitly calls for, and cable tunnel planted agent is without ponding or foreign material.Current check cable tunnel has or not ponding, and the way of taking is mainly manually to start the working method that cable tunnel cover plate is observed ponding.Because cable tunnel cover plate is heavier, start very effort, the personnel that strength is little cannot complete substantially, even if start reluctantly, also easily cause personal injury.Under the working condition in a current 110kV transformer station tour cycle on the 7th, cannot cable tunnel ponding situation be monitored in real time, be grasped.At present, there is no equipment can Real-Time Monitoring cable tunnel internal water accumulation situation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cable tunnel water level real-time monitoring device, the water level of described device in can Real-Time Monitoring cable tunnel, without staff, open cable tunnel cover plate and observe water level, reduced labour intensity, improved work efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cable tunnel water level real-time monitoring device, it is characterized in that comprising transformer, two above water level indicator lights and two above level switches, after a water level indicator light and a level switch series connection, form a liquid level and show branch road, plural level switch is positioned at different height, and two above liquid levels show that branch circuit parallel connection is on two output terminals of transformer.
Preferably, described device also comprises a level switch stationary magazine creel, and level switch is fixed on the differing heights position of level switch stationary magazine creel inside, and level switch stationary magazine creel is provided with inlet opening and wire hole.
Preferably, described level switch stationary magazine creel is square, and material is insulation fire proofing material.
Preferably, between described water level indicator light and transformer, and be provided with plug between water level indicator light and level switch.
Preferably, the output terminal of described transformer is parallel with relay indicating light.
Preferably, after protection diode, a water level indicator light and a level switch series connection, form a liquid level and show that branch circuit parallel connection is on two output terminals of transformer.
Preferably, described water level indicator light and level switch are provided with four.
The beneficial effect that adopts technique scheme to produce is: described device is used the different level switch of a plurality of height, and when liquid level meets or exceeds level switch, level switch is by closure, and corresponding water level indicator light is lit, the position of indication liquid level.By use described device can be clear and definite when water surface contact or flood cable, in the very first time, take the concrete measures, significantly improved the safety of equipment after water inlet.Solved simultaneously and will observe the problem that in cable tunnel, water level must manually be raised cable tunnel cover plate, effectively reduce the labour intensity in cable tunnel ponding observation work, and the personal injury while starting or putting back to cable tunnel cover plate in the work of thoroughly having stopped, and people enters contingent the suffocating in cable tunnel and waits danger.In addition, described device simple in structure, low cost of manufacture, has good popularization and prospect of the application.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, transformer 2, water level indicator light 3, level switch 4, level switch stationary magazine creel 5, plug 6, relay indicating light 7, protection diode.
Embodiment
As shown in Figure 1, a kind of cable tunnel water level real-time monitoring device, comprise transformer 1, four water level indicator lights 2 and four level switches 3, level switch is selected the side-mounted liquid level sensor of WYW-L1 type, also can use other can meet the liquid level sensor of the application's demand.After a water level indicator light 2 and level switch 3 series connection, form a liquid level and show branch road, four level switches 3 are fixed on the differing heights position of level switch stationary magazine creel 4 inside, level switch stationary magazine creel 4 is provided with inlet opening and wire hole, described level switch stationary magazine creel 4 is square, and material is insulation fire proofing material.Article four, liquid level shows that branch circuit parallel connection is on two output terminals of transformer 1.Water level indicator light is fixed on the convenient position of observing on cable tunnel external wall.
For easy to connect, between described water level indicator light 2 and transformer 1, and be provided with plug 5 between water level indicator light 2 and level switch 3.Whether the output terminal of described transformer 1 is parallel with relay indicating light 6, be used to indicate described device and work.Described device also comprises protection diode 7, and protection diode is connected on liquid level and shows on branch road.
Described device is used the different level switch of a plurality of height, and when liquid level meets or exceeds level switch, level switch is by closure, and corresponding water level indicator light is lit, the position of indication liquid level.By use described device can be clear and definite when water surface contact or flood cable, in the very first time, take the concrete measures, significantly improved the safety of equipment after water inlet.Solved simultaneously and will observe the problem that in cable tunnel, water level must manually be raised cable tunnel cover plate, effectively reduce the labour intensity in cable tunnel ponding observation work, and the personal injury while starting or putting back to cable tunnel cover plate in the work of thoroughly having stopped, and people enters contingent the suffocating in cable tunnel and waits danger.Described device can carry out Real-Time Monitoring to all house cables tunnel, cable shaft and cable passage internal water accumulation situation, can in any one be provided with the transformer station of cable tunnel and cable tunnel, popularize in an all-round way and use.
