Abstract
The utility model relates to an online switch cabinet cable head temperature detection apparatus characterized by comprising an insulated box body and a temperature sensing module disposed in the insulated box body. Two cable head inserting holes are disposed on a sidewall of the insulated box body. Two spiral chucking binding posts are arranged in the insulated box body. The opening positions of the spiral chucking binding posts correspond to the inserting holes. Two through holes are disposed on the top surface of the insulated box body in order that the screw heads of the spiral chucking binding posts can be exposed. The bottoms of the spiral chucking binding posts are connected through a conductive sheet. The detection probe of the temperature sensing module is arranged on the conductive sheet. The output end of the temperature sensing module is connected with an external wire through a RS485 interface circuit. The online switch cabinet cable head temperature detection apparatus may effectively detect the temperature of a cable head, transmit the temperature to a near-end machine via RS485 in short distance, prevent a wire on a detected end from exposing, and is easy to set and maintain.
Description
Technical field
The utility model relates to switch cabinet temperature detection technique field, particularly a kind of switch cubicle cable head temperature on-line measuring device.
Background technology
In the past about the monitoring of switchgear building, as the temperature monitoring at the positions such as cable splice, busbar joint, transformer contact, the high/low status monitoring that compresses switch, ambient temperature and humidity monitorings etc., adopt personal monitoring's way mostly, cannot accomplish Real-Time Monitoring like this.Along with the introducing of technology of Internet of things, by corresponding sensor is installed on power equipment, can accomplish the state of real time on-line monitoring power equipment, still, installation and the later maintenance of sensor become a difficult problem.
Utility model content
The purpose of this utility model is to provide a kind of switch cubicle cable head temperature on-line measuring device, and energy is the temperature of detection streamer head effectively, and can prevent that detected end wire from exposing by RS485 short-distance transmission to near-end machine, and setting, easy to maintenance.
The utility model adopts following scheme to realize: a kind of switch cubicle cable head temperature on-line measuring device, it is characterized in that: comprise an insulation box body and be arranged on the temperature sensing module in this insulation box body, on described insulation box body one sidewall, being provided with two cable end patchholes; In described insulation box body, be provided with two spiral card compact form binding posts; The bayonet socket position of described spiral card compact form binding post is corresponding with described patchhole; The upper surface of described insulation box body offers two through holes, to expose the spiral shell head of described spiral card compact form binding post; Bottom one conducting strip of described spiral card compact form binding post connects; On described conducting strip, be provided with the detection probe of temperature sensing module; The output terminal of described temperature sensing module connects external wire through RS485 interface circuit.
In the utility model one embodiment, at the bottom of described insulation box body comprises box and with the lid of clamping at the bottom of this box; Described through hole is arranged on this lid.
In the utility model one embodiment, described detection probe is the bottom that is embedded in described conducting strip.The utility model is simple in structure, by binding post heat conduction, and testing circuit and wire is arranged in insulation box body, not only easy for installation, and safety is set, and avoids professional to get an electric shock, and has good practical value.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is A-A cut-open view in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, this practicality is described further.
As shown in Figure 1, the present embodiment provides a kind of switch cubicle cable head temperature on-line measuring device, and its spy comprises an insulation box body 1 and is arranged on the temperature sensing module 2 in this insulation box body, on described insulation box body 1 one sidewalls, is provided with two cable end patchholes 3; In described insulation box body, be provided with two spiral card compact form binding posts 4; Bayonet socket 5 positions of described spiral card compact form binding post are corresponding with described patchhole; The upper surface of described insulation box body offers two through holes 6, to expose the spiral shell head 7 of described spiral card compact form binding post; Bottom one conducting strip 9 of described spiral card compact form binding post connects; On described conducting strip, be provided with the detection probe 10 of temperature sensing module; The output terminal of described temperature sensing module connects external wire 11 through RS485 interface circuit.
Please continue referring to Fig. 2, in figure, described spiral card compact form binding post 4 comprises copper tip 8 and spiral shell head 7; In order to facilitate later maintenance, in the present embodiment, at the bottom of described insulation box body comprises box and with the lid (meaning not shown in the figures) of clamping at the bottom of this box; Described through hole is arranged on this lid.
In order to reach better detection effect, allow detection probe large area touch conducting strip, in the present embodiment, described detection probe is the bottom that is embedded in described conducting strip.
The utility model in use, is fixed therein the cable conductor of access switch cubicle on a spiral card compact form binding post, the wire of another spiral card compact form binding post fixed outer electricity access cable; In use, conductor overheating passes to detection probe by binding post, and temperature sensing module is received a near-end machine by RS485 interface circuit by external wire 11.This near-end machine can be transferred to long-range middle control by signal by wireless or wired mode and hold.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
