There are various factors that affect the sealing of the electric meter box, mainly including the following aspects:

Installation position and structure of electric meter box: If the installation position of the electric meter box is incorrect, such as tilting or uneven base, it will cause the box cover to fail to close tightly, thereby affecting the sealing performance. In addition, the structural design of the electric meter box is unreasonable, such as the large clearance between the box cover and the box body, which can also lead to poor sealing.

Aging and damage of sealing ring: The sealing ring in the meter box is a key component to ensure sealing. However, the sealing ring will gradually age over time, resulting in hardening, brittleness, and other phenomena, thereby reducing its sealing performance. In addition, if the sealing ring is damaged during installation or use, such as scratches, tears, etc., it can also cause sealing failure.

Accumulation of debris and dust: debris and dust in the surrounding environment of the electric meter box may enter the box and accumulate on the contact surface between the sealing ring or box cover and the box body, thereby hindering the tight closure of the box cover and affecting the sealing performance.

Improper operation and maintenance: During the use of the meter box, improper operation, such as excessive force causing deformation of the sealing ring, or untimely maintenance, such as failure to regularly replace aging sealing rings, can affect the sealing performance of the meter box.

In summary, to ensure the sealing of the meter box, it is necessary to start from multiple aspects such as installation location, structural design, selection and maintenance of sealing rings, cleaning of the surrounding environment, and operating standards.
