The high-voltage power distribution outlet circuit of the production workshop has a total of 6 high-voltage outlet lines, as shown in the figure. Two of them are separated by two busbars through the isolating switch-circuit breaker to the No. 2 workshop substation; there is a route left busbar WB 1 via the isolating switch-circuit breaker for the No. 1 workshop substation; Busbar WB2 is connected to the No. 3 workshop substation through the isolating switch-circuit breaker; there is a high-voltage shunt capacitor bank for the reactive power compensation by a left-side busbar WB1 via an isolating switch, and a routing right-hand busbar WB2 via an isolating switch— The circuit breaker is used to power a group of high voltage motors. Since the high-voltage distribution lines here are all called by the high-voltage bus, the outlet circuit breaker needs to be equipped with an isolating switch on the side of the busbar to ensure the safe maintenance of the circuit breaker and the outgoing line.
Floating Board To Board Connector
FLOATING Board to Board Connector
FLOATING Board-to-board (BTB) connectors as the name indicates is used for connecting circuits board together. This kind of connectors are suitable for stacking circuits boards one over another. Flat flexible cables can be avoided using these kinds of connectors; moreover it makes the entire unit more compact. The commonly used BTB connectors are SMT connectors and Berg Strip. We will discuss about them in detail in the following section.
SMT CONNECTOR
Surface Mount Technology (SMT) connector is a commonly found board-to-board connector in advanced circuit boards. As the name indicates this connector is available only in surface mount model. It is carefully mounted on to the solder pads on the surface of the PCB.
SMT connectors are ideal candidate for miniaturization due to their small area of occupancy and stacking height. They are suitable for double layered or multilayered PCBs. They are designed for high performance and reliability.
They commonly found in advanced circuit boards in networking equipment, telephones, mobile phones, computers and other consumer electronics.
