Similarities and difference between insulator and insulating sensor
Insulators and insulation sensors are both key components in power systems, and they are both related and different.
common ground:
1. Function
I. The core function of both is insulation to prevent short circuits
II. Insulation materials should be made of high resistance materials and have a sufficiently long creepage distance
2. Design to withstand harsh environments
Anti pollution flashover: Umbrella skirt design increases creepage distance
Anti moisture flash: The surface is coated with a special waterproof layer, which can effectively prevent the formation of a water film in humid environments
Weather resistance: UV resistance, strong ability to withstand temperature differences
3. Structure
I. The structure of insulation and metal accessories used in the main body
II. The main insulation material is made of epoxy resin
III. Adopting mechanical support design, it needs to withstand the weight of the wire, wind force, etc
difference:
1. Functional differences
Insulators can provide support, and the main function of insulation sensors is to monitor the circuit status; In addition, insulated sensors can also output electrical signals.
2. Structural differences
Sensing elements have also been added to the insulated sensor
3. Different application scenarios
Insulators are mainly used for supporting busbars in transmission and distribution lines and substations. The advantage of insulation sensors is that they play a monitoring role in smart grids
In terms of fault prevention, insulators are passive protection and rely on regular manual inspections; Insulated sensors can provide real-time data and belong to active protection
4. Fundamental differences
Technical positioning: Insulators are basic insulation components, and insulation sensors are integrated accessories of "insulation+sensing"
Function: Insulators are devices used to ensure the safe operation of systems, and insulation sensors are used to predict faults
Therefore, in general, low-risk, low-cost distribution stations, insulators have stronger applicability; In some important distribution networks, insulation sensors are needed to play their important role.
