Description

Technical Field

[0001] The utility model relates to the technical field of magnetic induction, and particularly relates to a two-station magnetic induction module. Background Art

[0002] The live compartment refers to the shortest spatial distance between the live parts in electrical equipment or between the live parts and the grounded parts, ensuring the safe operation of electrical equipment. The importance of the electrical clearance lies in preventing the occurrence of discharge phenomena between the live parts and the grounded parts of electrical equipment, thereby ensuring the safe operation of electrical equipment. Preventing accidental entry into the live compartment means preventing accidental entry into the live isolation due to incorrect operation, which endangers personal safety. All previous accidents have been caused by accidental entry or non-compliance with operating requirements. Therefore, preventing incorrect operation is particularly important, and it is necessary to give a warning and cut off the power when opening the door. For this reason, we propose a two-station magnetic induction module. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a two-station magnetic induction module, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A two-station magnetic induction module includes a first housing and two groups of second housings. A control main board is arranged inside the first housing. Two wiring terminals are installed at the upper end of the control main board. An upper cover is installed at the upper end of the first housing. A sealing gasket is arranged at the lower end of the upper cover. A magnetic induction head is installed inside the second housing. A lid is fixedly connected to the upper end of the magnetic induction head. A stainless steel coated plastic corrugated pipe is connected between the second housing and the first housing.

[0006] Preferably, a stainless steel coated plastic corrugated pipe is opened at the upper end of the first housing. The stainless steel coated plastic corrugated pipe passes through the wiring groove and extends to the inside of the first housing. The inside of the wiring groove is sealed with epoxy resin.

[0007] Preferably, a mounting plate is fixedly connected to one side of the second housing. Threaded holes are opened at the upper end of the mounting plate.

[0008] Preferably, the two groups of second housings are respectively used for sensing the opening and closing signals of the door in the live compartment and the opening and closing of the power supply in the live compartment.

[0009] Preferably, a waterproof connector is fixedly connected to the front end of the first housing.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The double-station magnetic induction module is simple to install and connect. It realizes double detection through the magnetic induction heads of the double stations, provides double protection for the live compartments, and is effectively waterproof by epoxy resin potting. Due to the special use scenarios, it can be used both indoors and outdoors. Brief Description of the Drawings

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] As Figure 1-2 shown, the present utility model provides a technical solution: a double-station magnetic induction module, including a first outer shell 1 and two groups of second outer shells 7. A control main board 3 is arranged inside the first outer shell 1. Two groups of wiring terminals 4 are installed at the upper end of the control main board 3. An upper cover 6 is installed at the upper end of the first outer shell 1. A sealing gasket 5 is arranged at the lower end of the upper cover 6. A magnetic induction head 8 is installed inside the second outer shell 7. A lid 9 is fixedly connected to the upper end of the magnetic induction head 8. A stainless steel coated plastic bellows 10 is connected between the second outer shell 7 and the first outer shell 1.

[0017] In this embodiment, a stainless steel coated plastic bellows 10 is opened at the upper end of the first outer shell 1. The stainless steel coated plastic bellows 10 passes through the wiring groove 2 and extends to the inside of the first outer shell 1. The inside of the wiring groove 2 is potted with epoxy resin.

[0018] Specifically, the use of epoxy resin potting can effectively prevent water and ensure the stable operation of the module.

[0019] In this embodiment, a mounting plate 11 is fixedly connected to one side of the second outer shell 7. Threaded holes are opened at the upper end of the mounting plate 11.

[0020] Specifically, the second outer shell 7 can be conveniently installed through the mounting plate 11.

[0021] In this embodiment, two groups of second outer casings 7 are respectively used to sense the opening and closing signals of the door in the live compartment and the opening and closing of the power supply in the live compartment.

[0022] Specifically, double protection of the live compartment can be achieved through two groups of second outer casings 7.

[0023] In this embodiment, a waterproof connector 12 is fixedly connected to the front end of the first outer casing 1.

[0024] Specifically, the waterproof connector 12 can prevent water from entering the inside of the first outer casing 1.

[0025] It should be noted that during use, the wire is inserted into the inner side of the stainless steel corrugated pipe 10, then one end of the wire is connected to the magnetic induction head 8 inside the second outer casing 7, then the other end of the wire is connected to the terminal 4 inside the first outer casing 1, and then the other group of terminals 4 is connected to the external power supply line. The two groups of second outer casings 7 are respectively installed at the corresponding positions of the knife valves in the live compartment by using the mounting plate 11 to sense the opening and closing of the knife valves. When the door is opened, the signal and the power supply are completely disconnected. The signal disconnection realizes alarm warning, and the power supply disconnection realizes that the grounded metal partition automatically drops to cover the live static contact part, preventing the personnel entering the cabinet for maintenance from contacting the live part. After the switch grounding knife is closed, the mechanical interlock of the rear cabinet door allows the cabinet door to be opened, realizing double protection.

[0026] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
