Description

Technical Field

[0001] The utility model relates to the field of transformer safety maintenance, in particular to a transformer leakage monitoring and alarm device. Background Art

[0002] Transformer leakage can cause a variety of hazards. Leakage may lead to the risk of electric shock, direct harm to the human body, and cause fire. It may also eventually cause damage to equipment components or system failure, thereby affecting normal power transmission and equipment operation.

[0003] After searching, the patent announcement number is CN207021080U, which discloses a transformer leakage alarm device, whose structure includes a seismic support plate, a transformer body, an oil drain valve, a winding, an iron core, an oil tank, a radiator, a tap switch, a low-voltage bushing, a high-voltage bushing, a gas relay, an explosion-proof pipe, an oil level indicator, an oil storage cabinet, an alarm, and a thermometer. The seismic support plate is provided with a transformer body, and the explosion-proof pipe is composed of an explosion-proof pipe joint, a clamp, a pressure-resistant pipe, a high-voltage connecting piece, and a high-temperature resistant pipe. The thermometer is arranged in the transformer body. The beneficial effect of the utility model is that the explosion-proof pipe is provided, which has an explosion-proof function, can timely protect important electronic components when the equipment short-circuit explodes, and can suppress the explosion power, control the explosion range, effectively protect the staff, and reduce the economic losses of the enterprise.

[0004] In the existing technology, although a certain transformer protection effect can be achieved during use, there is a defect: the existing transformer lacks a double-layer protection effect, resulting in the inability to truly distinguish internal leakage or external leakage, affecting the smooth progress of subsequent repairs. In view of this, we propose a transformer leakage monitoring and alarm device to solve the above problem. Utility Model Content

[0005] The utility model aims to provide a transformer leakage monitoring and alarm device in view of the problems existing in the background technology.

[0006] The technical solution of the utility model is: a transformer leakage monitoring and alarm device, comprising a box body, a mounting plate 1, a mounting plate 2, a connecting line 1 and a connecting line 2, a mounting plate 1 is arranged on an inner wall of one side of the box body, an alarm 1 is arranged on the surface of the mounting plate 1, a mounting plate 2 is arranged on the outer wall of the box body, an alarm 2 is arranged on the surface of the mounting plate 2, and a main body is arranged inside the box body.

[0007] When the device is in use, the devices inside the mounting plate 1 and the mounting plate 2 can be used to protect the inside and outside of the box respectively. When there is internal leakage, when the current is weak, the current will enter the mounting plate 1 through the connecting wire 1. When the current reaches a certain value, then the protector 1 will protect, and the alarm will start, then it is known that there is a small internal current leakage, and the indicator light 1 will light up. When the current is too large, the current will also conduct the diode 2 on the side of the connecting wire 2, and then the protector 2 will protect, the alarm will start, and the indicator light 2 will light up, then it can be known that there is a large current leakage. When there is external leakage, that is, the external chassis is energized, the indicator light 3 will light up, and under the protection of the diode 1 and the diode 3, the current can be prevented from being conducted from the outside to affect the safety of the internal body.

[0008] Preferably, a base is provided at the lower end of the box body, and screws are provided on the surface of the base.

[0009] Preferably, a top plate is provided at the upper end of the box body.

[0010] Preferably, a connecting line 1 is provided between the main body and the mounting plate 1, and a fuse 1 is provided between the connecting line 1 and the alarm 1.

[0011] Preferably, a second connecting line is provided between the main body and the second mounting plate, and a second fuse is provided between the second alarm and the second connecting line.

[0012] Preferably, a diode 1 and a diode 3 are respectively disposed inside the connecting wire 1 and the connecting wire 2.

[0013] Preferably, indicator light 1, indicator light 2 and indicator light 3 are arranged on the upper end of the second mounting plate, and the indicator light 1, indicator light 2 and indicator light 3 are all connected to the internal circuit.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. The utility model can use three indicator lights to let the staff know the location of the leakage of the device, which is convenient and quick for maintenance.

[0016] 2. Based on the first beneficial effect, the device can use multiple diodes to form a unidirectional conduction circuit to prevent system failure caused by simultaneous internal and external leakage and prevent problems caused by poor maintenance.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
