Description

Technical Field

[0001] The utility model relates to the technical field of monitoring alarm devices, in particular to a monitoring alarm device for low-level power equipment failure. Background Art

[0002] Power equipment primarily includes two categories: power generation equipment and power supply equipment. Power generation equipment primarily includes power station boilers, steam turbines, gas turbines, hydro turbines, generators, transformers, and more. Power supply equipment primarily includes transmission lines of various voltage levels, instrument transformers, contactors, and more. There are numerous types of power equipment in a power system, and they are generally categorized into primary and secondary electrical equipment based on their different roles in operation.

[0003] Many electrical equipment in industrial and agricultural production (for example: high-voltage switchgear, high-voltage cables, etc.) operate under high voltage and high current conditions. Due to mechanical vibration, contact erosion and other reasons during use, the temperature of the contact may rise, causing oxidation at the contact, further increasing the contact resistance and temperature, followed by local welding or sparks or even arc discharge, affecting the surrounding insulation materials, and ultimately causing damage to the electrical equipment and causing accidents. Among the numerous power accidents, power outages and maintenance caused by local overheating of equipment often occur. Therefore, it is necessary to monitor the temperature of power equipment and implement power equipment operation status monitoring and fault diagnosis technology.

[0004] When detecting faults in low-level power equipment, a monitoring alarm device is required for monitoring. However, when the monitoring alarm device is in use, the height of the temperature monitoring head on the monitoring alarm device cannot be adjusted according to demand, which results in the monitoring alarm device being unable to monitor the temperatures at different locations in the low-level power equipment, resulting in poor monitoring effect of the monitoring alarm device on the low-level power equipment. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a monitoring and alarm device for low-level power equipment faults, which has the advantages of adjusting the height of the temperature monitoring head to monitor different positions, and solves the problem that the height of the temperature monitoring head cannot be adjusted.

[0006] The cam is provided with a plurality of movable members on the upper and lower surfaces of the movable members, and the movable members are provided with a plurality of movable members on the upper and lower surfaces of the movable members. When the height of the temperature monitoring head needs to be adjusted to the required monitoring height, the pull plate is released, and the fixing ring is driven to move inward by the inertia of the spring, and the fixing ring is driven to move inward by the fixing ring. When the fixing ring moves to the hole in the protrusion, the concave plate can be driven to fix the concave plate. At this time, the temperature monitoring head on the concave plate can monitor the temperature of this position, so that the temperature of different positions in the low-level power equipment can be monitored more accurately.

[0007] The utility model discloses a monitoring and alarm device for low-level power equipment failure, wherein an alarm is provided on the top of the front of the connecting plate, and a controller is provided on the bottom of the front of the connecting plate. The input end of the controller is electrically connected to the temperature monitoring head, and the output end of the controller is electrically connected to the alarm. When the temperature monitoring head detects that the temperature is too high, the utility model first transmits the information to the controller through the temperature monitoring head. After the controller receives the information, the controller controls the alarm to sound an alarm. After the staff hears the alarm, the staff rushes to the required position of the low-level power equipment in time to dissipate heat, thereby avoiding the high temperature in the low-level power equipment, which in turn causes oxidation at the contact point, further increases the contact resistance, and further increases the temperature, followed by local welding or sparks or even arc discharge, which affects the surrounding insulating materials and ultimately causes damage to the electrical equipment and causes accidents.

[0008] The utility model discloses a monitoring and alarm device for low-level electrical equipment faults, wherein the back of the alarm is fixedly connected to a fixing plate, and the inner cavity of the fixing plate is fixedly connected to the connecting plate by fixing bolts. The fixing plate and the fixing bolts can fix the alarm, so that the alarm is more effective when in use, and avoids the alarm from loosening during use, which may cause the alarm to fall off.

[0009] The utility model discloses a monitoring and alarm device for low-level power equipment faults, wherein the connection between the front surface of the concave plate and the temperature monitoring head is fixedly connected by a connecting block, and the temperature monitoring head is located at the center of the front surface of the concave plate. The connecting block can fix the temperature monitoring head, so that the temperature monitoring head is more effective when in use, and avoids the temperature monitoring head from becoming loose during use, which may cause the temperature monitoring head to fall off.

[0010] The utility model discloses a monitoring and alarm device for faults of low-level electrical equipment, wherein the top and bottom of both sides of the connecting plate are fixedly connected with mounting plates, and the inner cavity of the mounting plate is provided with mounting holes. The mounting plates can facilitate the installation of the connecting plate, thereby avoiding the inconvenience of installing the connecting plate in the low-level electrical equipment.

[0011] The utility model relates to a monitoring and alarm device for low-level electric power equipment failure, wherein nine clamping holes are equidistantly provided on both sides of the concave plate, and the nine clamping holes are of the same size.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When the temperature monitoring head is adjusted to the required monitoring height, the pull plate is released, the fixing ring is driven to move inward by the inertia of the spring, and the fixing ring is driven to move inward by the fixing ring. When the fixing ring moves to the locking hole in the protrusion, the concave plate can be fixed. At this time, the temperature monitoring head on the concave plate can monitor the temperature of this position, so that the temperature of different positions in the low-level power equipment can be monitored more accurately.

[0014] 2. When the temperature monitoring head detects that the temperature is too high, the utility model first transmits the information to the controller through the temperature monitoring head. After the controller receives the information, it controls the alarm to sound an alarm. After the staff hears the alarm, they rush to the location where the low-level power equipment needs to be cooled in time, avoiding the high temperature inside the low-level power equipment, which in turn causes oxidation at the contact, further increases the contact resistance, further rises the temperature, and then causes local welding or sparks or even arc discharge, which harms the surrounding insulation materials and ultimately causes damage to the electrical equipment and causes accidents;

[0015] The connection block can fix the temperature monitoring head, so that the temperature monitoring head can be used more effectively and avoid the temperature monitoring head from becoming loose during use, which may cause the temperature monitoring head to fall off.

[0016] The fixing plate and the fixing bolts can fix the alarm, so that the alarm works better when in use and avoids the alarm from becoming loose during use, which may cause the alarm to fall off.

[0017] The installation plate can facilitate the installation of the connecting plate, thereby avoiding the inconvenience of installing the connecting plate in low-position power equipment. BRIEF DESCRIPTION OF THE DRAWINGS

When the monitoring and alarm device of the utility model is used, the connecting plate 1 is first installed at the required position in the low-level power equipment, and then the temperature monitoring head 605 is used to monitor the temperature of the low-level power equipment. The temperature inside the low-level power equipment is monitored. When the height of the temperature monitoring head 605 needs to be adjusted, the pull plate 604 is first pulled to drive the clamping rod 608 to move outward through the pull plate 604, and the fixing ring 6010 is driven to move outward through the clamping rod 608. The movable groove 606 and the slide rod 609 in the concave plate 601 cooperate with the fixing ring 6010 to move outward, and the fixing ring 6010 can be driven by the spring 607 to squeeze. When the clamping rod 608 moves out of the clamping hole 2 in the protrusion 3, the concave plate 601 is moved, and the concave plate 601 is moved through the slide groove 7 in the protrusion 3 and the slider 602.

After the controller 5 receives the information, the alarm 8 is controlled by the controller 5 to sound an alarm. After the staff hears the alarm, the staff rushes to the required position of the low-level power equipment in time to dissipate heat, avoiding the high temperature in the low-level power equipment, which in turn causes oxidation at the contact point, further increases the contact resistance, and further increases the temperature, followed by local welding or sparks or even arc discharge, which affects the surrounding insulating materials and ultimately causes damage to the electrical equipment and causes accidents.
