摘要： Respective contact terminals in respective arc-suppressing spaces of respective breakers are opened at a voltage zero point of any phase of three phases, simultaneously among the three phases. If current breaking is carried out for the three phases at the same time, when the breakers of the three phases are opened, the residual magnetic levels of the respective phases of a transformer can be controlled so that the residual magnetic flux level of the phase opened at the voltage zero point is maximum (for example, −2 K or +2 K) and the residual magnetic flux level of the other two phases are opposite in polarity to the residual magnetic flux level of the phase concerned and equal to substantially the same residual magnetic flux (for example, +K and +K or −K and −K) which is equal to about one half of the residual magnetic flux level of the phase concerned. Accordingly, by throwing the phase broken at the voltage zero point at a first time, the difference in residual magnetic flux between the second throwing phase and the third throwing phase just after the first phase is thrown can be substantially nullified.

摘要： A closing phase that produces the smallest energization flux error at a connection input point is calculated based upon a residual flux of the first closing phase and the preliminarily given pre-arc characteristic and closing time deviation characteristic of a three-phase circuit breaker, so that the calculated phase value is set as a target closing phase of the first closing phase. A closing phase that produces the smallest energization flux error when a residual flux of zero is calculated, so that the calculated phase value is set as a target closing phase of the remaining two phases. The total time required from the reference point to the target closing phases of the remaining two phases and a delay time corresponding to an integer multiple of a given cycle of the three-phase power supply is set as a target closing time of the remaining two phases.

摘要： This invention provides a polyester and a polyester molded product, which, while maintaining color tone, transparency, and thermal stability, can realize a high polycondensation rate, are less likely to cause the production of polycondensation catalyst-derived undesired materials, and can simultaneously meet both quality and cost effectiveness requirements, which can exhibit the characteristic features, for example, in the fields of ultrafine fibers, high transparent films for optical use, or ultrahigh transparent molded products. These advantages can be realized by using, in the production of a polyester in the presence of an aluminum compound-containing polyester polycondensation catalyst, an aluminum compound having an absorbance of not more than 0.0132 as measured in the form of an aqueous aluminum compound solution, prepared by dissolving the aluminum compound in pure water to give a concentration of 2.7 g/liter in terms of the amount of aluminum element, under conditions of cell length 1 cm and wavelength 680 nm.

摘要： A gas-circuit breaker includes a cylinder, a stationary piston, and a moving piston. The cylinder has a moving contact that is fixed on one end of a rod and has a gas exhaust that faces a stationary contact. The rod is inserted into the cylinder. The stationary piston is fixed to the container, and is fitted in an opening of the cylinder to create a puffer chamber. Due to movement of the rod, the stationary piston compresses arc-extinguishing gas, and the gas blows onto the arc through gas exhaust. The moving piston partitions the puffer chamber into a first puffer chamber and a second puffer chamber. Sliding of the moving piston changes the capacity of the first puffer chamber and the second puffer chamber according to the difference in pressure in the first puffer chamber and the second puffer chamber.

摘要： A puffer-type gas blast circuit breaker is capable of restraining reduction in creepage insulation resistance of an insulating support and an insulating rod due to insulating gas of high temperature. An electrode section is mounted on a stationary member supported on an insulating support, and a stationary side arc contact and moving side arc contact are disposed facing each other to contact and separate; a hollow piston rod and an insulating rod are connected to the moving side arc contact, and inserted in a stationary member body portion; and a gas flow blocking member is mounted on an end of the piston rod to prevent an insulating gas heated and coming to the stationary side from getting into the insulating rod side. The stationary member body portion is formed cylindrical so that a gap between the body portion of the stationary member and the gas flow blocking member is minimized.
