An Isolated Transfer Switch is a device that is used to safely connect or disconnect a generator or other power source from a main electrical panel. This type of switch is beneficial because it prevents voltage spikes and other electrical problems that could damage equipment or injure people. Additionally, an Isolated Transfer Switch can be used to provide backup power in the event of a power outage.
what do you know about Solar energy Isolated Transfer Switch?
How to connect with Isolated Transfer Switch correctly?
What is the use and maintenance process of Isolated Transfer Switch?
Solar energy has been used for centuries, but it was only recently that we have begun to harness its power on a large scale. Solar energy is now one of the most promising renewable energy sources, with the potential to meet a significant portion of the world’s energy needs. One of the key components of a solar energy system is the Solar Isolated Transfer Switch (SITS). The SITS is a switch that is used to isolate the solar panel array from the rest of the electrical grid during maintenance or power outages. In this blog post, we will explore how the SITS works and its importance in solar energy systems.
Locking the control wiring of the isolating switch with the corresponding circuit breaker can effectively prevent the isolating switch from being pulled and closed under load. However, in the operation of the Isolated Transfer Switch on the bus side and the isolating switch on the line side, due to human reasons, the operation sequence may be reversed, which is not allowed by the principle of switch and knife switch operation, and is also one of the causes of accidents in the power system. In order to prevent the operation sequence of the isolating switch from being reversed, the control wiring of the original isolating switch is improved for factories and stations that do not adopt the program lock to prevent mistakes, which can prevent misoperation and reduce unnecessary accidents.
In the Isolated Transfer Switch control and blocking circuit, connect the isolation switch auxiliary contact in series, that is, in the bus side isolating switch control locking circuit, connect the line side isolating switch normally closed auxiliary contact in series, and the line side isolating switch control circuit in series in the bus side Isolated Transfer Switch normally open auxiliary contact.
1) Clean the dust on the surface of the porcelain parts, check whether the surface of the porcelain parts is glazed, damaged, whether there are cracks and flashover marks, and whether the iron-porcelain joint of the insulator is firm. If the damage is serious, it should be replaced;
2) Use gasoline to wipe off the oil stains on the blades, contacts or fingers, and check whether the contact surface is clean, whether there are mechanical damage, oxidation and overheating traces, distortion, deformation, etc.;
3) Check whether the contacts on the Isolated Transfer Switch or the accessories on the blade are complete and whether they are damaged;
4) Check whether the leads connecting the Isolated Transfer Switch to the busbar and the circuit breaker are firm and whether there is any overheating phenomenon.
