UPS is the battery (maintenance-free lead-acid batteries, mostly) and the host is connected to the host via an inverter module converts the DC circuit mains system equipment
Power supply is mainly used for a single computer, computer network systems, or other power electronic devices such as solenoid valves, pressure transmitters provide a stable, uninterrupted
Online means regardless of the grid voltage is normal, the load to go through with the AC voltage inverter circuit, inverter circuit that is always active, on-line double conversion UPS generally structure. The so-called double-conversion high frequency online ups refers to normal working hours, power through the AC / DC, DC / AC conversion twice and then supplied to the load.
This UPS uninterruptible power supply so that the inverter has been in working condition, it is first converted by circuitry external AC to DC, and then through the high quality of the inverter to convert DC into high quality sine wave AC output to the computer. Online UPS power supply situation in the main function is regulated and prevent radio interference, while the battery charge management; backup during power outages using a DC power source (battery) power to the inverter. Since the inverter has been at work, so there is no problem switching time for the power supply, there are strict requirements of the occasion.

Pre-installed piping

Pre-installed piping
1. Introduction pipeline
(1) two-director and branch pipes: From lubrication pump out until all the oil inlet distributor, relatively high under pressure. Usually cold drawn seamless steel pipe, the material is 10 or 15 gauge steel. Severe corrosion of the pipe must not be used;
(2) to the pipeline: from the distributor to all lubrication points out the inlet (bearing hole), under pressure is relatively low. Usually drawn copper, easy to bend when the pipe. There is also cold drawn seamless steel or stainless steel pipe;
(3) the use of hose high frequency online ups encountered active site connections.
2. The piping layout requirements
(1) pipeline to try to avoid the heat radiation and cooling water temperature is too high or too low, such as spraying of the Department, particularly hose fittings;
(2) piping and other equipment should not affect the operation of the host, to be safe, reliable, easy to work, observations, maintenance;
(3) To smooth vertical and horizontal piping, neat appearance. As little as possible, or small-angle bend elbows, using a large arc, thus reducing oil flow resistance;
When the conflict (4) installation occurs, a small tube let bassoon, low-pressure pipe so that high-pressure pipe;
(5) the pipeline can not be contacted at the intersecting should spaced;
(6) parallel pipe joints should be staggered installation, to avoid affecting the installation and removal;
(7) In order to facilitate disassembly pipeline cleaning, the union should be properly installed, but to use less, reducing the possibility of leaks.
3. Determine the length of the tube
(1) determined in accordance with 8.2 fixed piping path, the length of the tube was measured in the field, pay attention to the size of the bend radius of influence;
(2) make different types of pipe industrial ups system access after effects into account;
(3) to determine the length of the tube should be piecemeal, cut, pre-order to facilitate on-site adjusted according to actual situation, if all of a sudden cut off, the accumulated error occurs when the pipe is difficult;
(4) short pipe cut at all need to try to take advantage of the short tube where, if necessary, can be used to take a long straight pipe joints, joints should be less but not much on the tube segment.

 

To develop solar inverter system, must first understand the solar

To develop solar inverter system, must first understand the solar (PV cells) of different characteristics is very important. PV cell model as shown in Fig. Parasitic resistance Rp and Rs is, in the ideal case of zero and infinity, respectively.
Light intensity and temperature can significantly affect the operating characteristics of PV cells. Current proportional to the light intensity, but the impact of changes in the light of the operating voltage is very small. However, the operating voltage is affected by temperature. Battery temperature will reduce the operating voltage, but the current generation of little influence. The figure below illustrates the effect of temperature and light on PV modules.
Effect of temperature and light on the PV module
Effect of light intensity on the battery output high frequency online ups greater than the impact of temperature changes. This is all common PV materials are applicable. Important result of these two effects upon binding to, PV battery Solar panel inverter will decrease with the decrease of light intensity and rise / or temperature.

High frequency online UPS applications

High Frequency Online UPS: from basic application in principle, UPS is a storage device containing, as the main component in the inverter, power protection devices output voltage constant frequency. Home inverter UPS rectifier mainly consists of several parts, batteries, inverter and static switch and other components.Home inverter ups  Rectifier: Rectifier is a rectifier unit, simply means that the alternating (AC) into direct current (DC) devices. Home inverter and high frequency online UPS UPS has two main functions: High Frequency Online UPS High Frequency Online UPS first,Home inverter ups alternating current (AC) into direct current (DC), after filtering supply load, Home inverter ups or supply inverters;Home inverter ups  high frequency online UPS second, high frequency online UPS to provide battery charging voltage. Therefore, high frequency online UPS which at the same time play the role of a charger; domestic inverter UPS Battery: High frequency online UPS UPS batteries are used as energy storage devices, home inverter UPS it consists of several cells connected in series together, determine its capacity to maintain the size of the discharge (supply) time. High frequency online UPS and its main function is: when the mains is normal, the energy is converted into chemical energy stored in the battery. Household solar inverter mains failure, the chemical energy into electrical energy supplied to the inverter or load; Home inverter ups Inverter: Popular speaking, high frequency online UPS and inverter is a direct current (DC) into alternating current (AC) device. It consists of an inverter bridge control logic and filtering circuits; static switch: static switch, also known as static switch, Home inverter ups home solar inverter which is a non-contact switch, with two thyristor (SCR) antiparallel an AC switches consisting of its closing and opening controlled by logic controller. Home solar inverter high frequency online UPS models into transformational and two. High frequency online UPS converter switching power supply is mainly used for two-way system, its role is automatically switched from the road all the way to the other;Home inverter ups  and models switch is mainly used in parallel with the mains power inverter or multiple inverters devices.
