Abstract
The invention discloses a cable trench inflow monitoring device for a transformer station. The cable trench inflow monitoring device includes a buoy, indicating lamps, reed switches, and a power supply. The buoy is arranged at the bottom of a cable trench and is provided with a strong magnet. The number of the indicating lamps is four, and the number of the reed switches is four. The four reed switches are vertically and adjacently arranged in the same line. The four indicating lamps are respectively connected to the reed switches through leads and are serially connected with the power supply. The cable trench inflow monitoring device for the transformer station has simple structure and reasonable design. The buoy with the strong magnet corresponds to the reed switch, so that a circuit where the indicating lamps are is conducted. The indicating lamps further display corresponding colors, and staff determines the water depth condition in the cable trench according to the displayed colors of the indicating lamps in order to perform corresponding treatments timely. The cable trench inflow monitoring device for the transformer station can display the water level condition in real time, greatly facilitates the daily work of the staff, and guarantees the safety of electric power operation systems.
Description
Technical field
The invention belongs to the cable duct technical field of transformer station, particularly relate to a kind of cable duct of substation water inflow monitoring device, be applicable to 35 kilovolts and above transformer station.
Background technology
Cable duct is the underdrain can opened for cabling, cover plate, for the protection of cable not by pressure injury.Because cable duct is positioned at subsurface, easily ponding is caused under long-term behavior, particularly during rainy season, once there is ponding in cable duct, easily there is crust for a long time and chap in cable, finally cause cable insulation to damage, cause the generation of accident in the immersion of water, therefore, a kind of cable duct water level monitoring and alarm system that is used for of invention seems particularly important.
Summary of the invention
In order to solve problems of the prior art, the object of this invention is to provide a kind of cable duct of substation water inflow monitoring device, this monitoring device can water level conditions in time in warning cable ditch.
In order to realize foregoing invention object, the present invention adopts technical scheme as described below:
A kind of cable duct of substation water inflow monitoring device, comprise cursory, pilot lamp, tongue tube and power supply, describedly cursoryly be placed on bottom cable duct, described cursory on be provided with strong magnet, shown pilot lamp is provided with four, tongue tube is provided with four, and four tongue tubes go to upper and lower next-door neighbour arranges and be located along the same line, four pilot lamp respectively by wire connect after a tongue tube with power series.
Further, the described cursory tongue tube corresponded to bottom.
Further, the distance bottom first tongue tube distance cable duct is from top to down 0.6 meter, and the distance bottom second tongue tube distance cable duct is 0.4 meter, and the distance bottom the 3rd tongue tube distance cable duct is 0.2 meter.
Further, described cursory on be provided with spacing rope.
Further, described cursory be loop configuration, in cursory center pit, be equipped with guide pole, guide pole is installed in bottom cable duct.
Further, described four pilot lamp show four kinds of different colors when lighting.
Owing to adopting technique scheme, the present invention has following superiority:
Structure of the present invention is simple, reasonable in design, by the cursory next corresponding tongue tube with strong magnet, make the loop conducting of pilot lamp place, and then make pilot lamp show corresponding color, staff determines the depth of water situation in cable duct according to the color that pilot lamp shows, to make corresponding process in time, the present invention can show water level conditions in real time, greatly facilitate the routine work of staff, ensure that the safety of operation power system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is circuit theory diagrams of the present invention;
In figure: 1-power supply; 2-pilot lamp; 3-tongue tube; 4-is cursory; 5-strong magnet; 6-guide pole.
Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 1, 2, a kind of cable duct of substation water inflow monitoring device, comprise cursory 4, pilot lamp 2, tongue tube 3 and power supply 1, described cursory 4 are placed on bottom cable duct, be provided with strong magnet 5 on described cursory 4, shown pilot lamp 2 is provided with four, and tongue tube 3 is provided with four, and four tongue tubes 3 go to upper and lower next-door neighbour's layout and are located along the same line, and are connected in series after four pilot lamp 2 connect a tongue tube respectively by wire with power supply 1.
Described cursory 4 correspond to tongue tube 3 bottom.
First tongue tube 3 is from top to down 0.6 meter apart from the distance bottom cable duct, and second tongue tube 3 is 0.4 meter apart from the distance bottom cable duct, and the 3rd tongue tube 3 is 0.2 meter apart from the distance bottom cable duct.
Spacing rope is provided with on described cursory 4.
Larger displacement is produced in floating-upward process again in order to prevent cursory 4, cursory 4 are set to loop configuration, in the center pit of cursory 4, be equipped with guide pole 6, guide pole is installed in bottom cable duct, by guide pole can make cursory on strong magnet corresponding with tongue tube all the time.
For the ease of observing and instruction, described four pilot lamp show four kinds of different colors when lighting, as blue, yellow, orange, red, the blue tongue tube corresponded to bottom, yellow indicator lamp corresponds to the tongue tube at 0.2 meter of, orange indicating light corresponds to the tongue tube at 0.4 meter of, the tongue tube at corresponding 0.6 meter of of red led.
When not intaking in cable duct, the cursory bottom being positioned at cable duct, now, under the effect of the strong magnet on cursory, makes first pilot lamp that tongue tube is connected in series light from bottom to top; When intaking in cable duct, cursory floating, when corresponding to second tongue tube, the pilot lamp that second tongue tube is connected in series lights, and now staff can determine that the water level in cable duct is 0.2 meter; When cursory floating up to corresponding to the 3rd tongue tube, the 3rd pilot lamp that tongue tube is connected in series lights, and now staff can determine that the water level in cable duct is 0.4 meter, needs to carry out drainage sunk well; When cursory floating up to corresponding to the 4th tongue tube, the 4th pilot lamp that tongue tube is connected in series lights, and staff can determine that the water level in cable duct is 0.6 meter, now just needs to carry out urgent drainage sunk well.
In addition, due to cursory and on strong magnet there is certain height, therefore spacer block can be set between adjacent tongue tube, cursory in floating-upward process to prevent, when passing through the junction of adjacent tongue tube, having two pilot lamp and lighting, to make the concrete height being not easy to judge water level.
