| 63 | Time delay device | US09309374 | 1999-05-11 | US06201676B1 | 2001-03-13 | Michael D. Glaser |
| A hydraulic time delay device couples to a fault-sensing element in a circuit recloser. The time delay device includes a piston that has an external connection and is operable to move through a housing in the device to cause hydraulic fluid in the housing to flow out of the housing and into a passageway. The time delay of the time delay device corresponds to a time required to move the piston. A first adjustable orifice is formed the passageway to define an adjustable first fluid flow path through the passageway. An adjustable valve is positioned to provide an adjustable second fluid flow path through the passageway. A second adjustable orifice is formed in the passageway to provide further adjustment of the second fluid flow path. Adjustment of the first orifice, the valve, and the second orifice affect the time required to move the piston. | ||||||
| 64 | Molded case circuit breaker with contact bridge slowed down at the end of repulsion travel | US25112 | 1993-03-02 | US5310971A | 1994-05-10 | Denis Vial; Jean Bonfils; Marc Rival |
| The contact bridge of a molded case circuit breaker is rotatably mounted in a bar by two springs arranged symmetrically from the rotation axis. Each spring is, on the one hand, anchored to the contact bridge, and, on the other hand, anchored to a rod housed in a notch of the bar. The same springs provide contact pressure and slowing-down of opening of the contact bridge at the end of repulsion travel by electrodynamic effect. The contact bridge bears on its edge cam surfaces which, at the end of opening travel, engage the anchoring rods to move them in the notches in the elongation direction of the tension springs. The energy of the contact bridge is thus taken up and stored in the springs causing slowing-down of the contact bridge. The profile of the cams can be chosen to enable reclosing of the contact bridge, this reclosing naturally being delayed by the slowing-down effect at the end of travel. The cam profile can also ensure latching of the contact bridge in the open position. | ||||||

| In a selective safety device for the protection of successive power levels in a power distribution system, a current limiting switch is provided in each of the power levels and includes a current-limiting quick-switching contact which is so positioned at the power supply side in each one of the different power levels such that the current limiting switch immediately in front of a fault is switched off upon occurrence of a fault. A resistor is connected across each of the quick-switching contacts and is serially connected in the interrupted circuit upon the opening action of the quick-switching contact. Additionally, a slow-switching contact is serially connected with each of the quick-switching contacts to be opened after opening of the quick-switching contact with a presettable delay time, which is dependent upon the power levels in which the slow-switching contact is connected. The resistor across the quick-switching contacts includes at least two serially connected resistance conductors which are gradually introduced in the interrupted circuit by the arc formed between the resistance conductors upon opening of an associated quick-opening switching contact. | ||||||

| 75 | Circuit Breaker for hierarchically controlling short-circuit current and trips | US15233949 | 2016-08-10 | US20170047183A1 | 2017-02-16 | Xin Li; Bochen Li; Bolin Li |
| The invention discloses a short circuit current hierarchical control tripping parameter circuit breaker. According to the invention, resistance of an alloy magnetic resistance body is changed through circuit current, and contract control can be carried out on short-circuit current. The control range of the circuit breaker can achieve that no magnetic resistance will be generated when current is no more than 8 times of rated operational current, and current limiting may be realized by the magnetic resistance when current is 8 times more than rated value. In this way, hierarchical control on short-circuit current of different levels of circuits can be carried out, and short-circuit current can be limited in a predetermined range, thereby restricting the short-circuit current in a predetermined range, solving a problem of power supply flickering, and avoiding large-area power failure accidents caused by override trip existing in an electrical control switch. | ||||||
