1,
Dust is carried into the machine and deposited.
When the air is wet, it can cause the host to control the disorder to cause the host to work abnormally, and an inaccurate alarm occurs. A lot of dust can also cause the device to have poor heat dissipation. It should be thoroughly cleaned once every quarter. The second is to check the looseness and loose contact of the connectors and connectors during dust removal.
2 , although the energy storage battery packs are used
Maintenance-free battery, but this only eliminates the previous measurement, ratio, and timing addition
Distilled water work. But external factors
The influence of the working state on the battery has not changed, and the influence of the abnormal working state on the battery has not changed. This part of the maintenance work is still very important.
The UPS power system maintenance and repair work is mainly in the battery part.
3 , the work of energy storage batteries are all in the floating state, in which case discharge should be performed at least once every quarter. The battery pack should be charged prior to discharge to achieve the balance of the entire battery pack. Be aware of the battery that is already present in the pack before discharging. If any one of the discharge termination voltages is reached during discharge, the discharge should be stopped. Continue discharging to eliminate the backward batteries and then discharge them.
Checking for electrical discharges is not the first pursuit of the percentage of discharged capacity. Instead, attention must be paid to the discovery and handling of backward batteries. This can prevent accidents, so as to avoid backward battery deterioration in discharge is a reverse battery.
4 , usually at least each battery should have
Eight batteries are used as the indicator battery. As a reference for understanding the working status of the full battery pack, the marked battery should be measured and recorded regularly.
5. Routine items to be inspected during routine maintenance include: cleaning and testing voltage and temperature at both ends of the battery; whether there is looseness at the connection, corrosion phenomenon, or pressure drop of the connection strip; whether the appearance of the battery is intact, and there is no shell deformation and leakage; Whether there is acid mist around the pole or safety valve; whether the host equipment is normal.
6 , maintenance-free battery to maintain, is not an absurd argument, we should proceed from a broad perspective of maintenance, to ensure that the operation, day-to-day management of the thoughtful, detailed and normative, to ensure equipment (including
The host equipment) maintains a good operating condition, thereby extending the service life; ensuring that the DC bus always maintains acceptable voltage and battery discharge capacity; and ensuring battery operation and personnel safety and reliability. This is the purpose of battery maintenance. It is also the content and rules that are included in the battery operation procedures.
Our company owns independent intelligent intellectual property testing instruments to provide customers with safe, efficient and convenient power quality inspection and maintenance services.
Overshot go into the heart of the drill pipe, the slider move up, make the tube socket head can be inserted into the center, when on the slider move up tight, using friction lift drill, remove loose again after the slider, by means of the connection string to slide along the block should tighten, set aside the center pipe, but in front of the salvage must first determine the bit in the bottom of the hole position, can be in a thin plate with bolts tight end of drill pipe, Drop the drill pipe to the bottom of the hole and press it on the drill bit. After waiting for a moment, it is proposed that the relative position of the drill bit at the bottom of the hole and the center of the rotary plate of the drill can be determined by observing the indentation left by the center pipe of the drill bit on the board, and then move the drill or rotary plate so that the center of the rotary plate is directly in front of the center pipe of the injured head, so as to ensure that the fishing device can be inserted into the center pipe accurately.
