Connection Technology of Valve-regulated Sealed Lead-acid Batteries
Valve-regulated sealed lead-acid batteries have DC voltage in open circuit state and store certain energy. The short circuit of positive and negative current is theoretically infinite enough to melt electrodes, damage installation tools (such as wrenches) and ignite. If there is no easy break point in short circuit circuit circuit, short circuit phenomenon can not disappear in time, battery connection line will be long-term. When the protective layer is melted by overcurrent, the battery plate bends and deforms until it burns, resulting in fire accidents. When installing non-standard Xiukang UPS system,
The DC voltage of YUASA ups battery is in open circuit state and stored a certain amount of energy. The positive and negative short circuit currents are theoretically infinite enough to melt the poles and damage the installation tools (such as wrenches). At the same time, it will ignite, such as there is no easy breakpoint in the short circuit circuit circuit, the short circuit phenomenon can not disappear in time,YUASA ups battery connection line will melt the protective layer due to long-term overcurrent, the battery plate will bend and deform until burning, resulting in fire accidents. When installing non-standard Xiukang UPS system, DC short circuit is caused by some reason, and battery burnout accident occurs when circuit breaker in circuit breaker fails again is not uncommon. I think everyone has realized the seriousness of short circuit in batteries. Here we go. Batteries are dangerous to install, but they can be easily installed as long as the head is kept clean.
Next, share with you Tangshao UPS battery connection skills.
First of all, the mind should be clear, the installation environment should be clean, people should be few, do not have any ideas, the connection plan should be clear, mobile phones should be closed during installation, do not chat with customers, and can not answer curious customers chat with installation. A series of problems, which can distract attention, are prone to accidents;
Tangshao UPS batteries should be physically inspected in front of the shelf and measured open circuit voltage to avoid rework. When one end of the cable is connected to the battery, the other end should be insulated or held. The palm of the hand prevents fire where it should not be placed.
One end of the connection line should be connected to the pole to be connected. Even if it is wrong, it can only be connected to the pole. It will not be a catastrophe on the upper and connecting lines, or zero can be connected by measuring the pressure difference between the two points to be connected.
When two people are connected at the same time, the corresponding UPS battery pack or potential relationship should be connected. Because two people are at the same potential (or at any time become the same potential, such as touching the battery seat at the same time), if there is a potential difference between the connected batteries, then the battery and two people form a circuit, and electric shock may occur.
After series connection, the voltage between positive and negative voltage of
YUASA ups battery group is relatively high. When connected to the MCCB (battery switch), each line should be connected to the MCCB first, then to the corresponding battery end; or rest in the battery pack. Point, complete the connection between MCCB and UPS battery packs, and then connect breakpoints. For multiple parallel battery packs, each group should be disconnected. After connecting MCCB terminals, use multimeter to detect polarity, and then connect the disconnected terminals.
