Abstract
The utility model discloses a connectiondisconnection device connected with a passive component in parallel, and is characterized by comprising the passive component and the connectiondisconnection device (S1), wherein the passive component is connected in parallel between an inlet-wire terminal (1) and an outlet-wire terminal (2) of the connectiondisconnection device (S1). According to the utility model, when the commercial power is existed and a low-voltage breaker or a switch device is disconnected, a tiny current signal is generated by the passive component, and if a current signal is detected by electric equipment while the device is disconnected, it is determined that the commercial power is existed in the power grid before the inlet-wire point of the device, and if no current signal is detected in the circuit by the electric equipment, it is determined that the commercial power is not existed in the power grid before the inlet-wire point of the device. The connectiondisconnection device connected with the passive component in parallel improves the power continuity, and is simple in structure and convenient in mounting and maintenance, being applicable in various occasions.
Description
Technical field
The utility model relates to a kind of circuit arrangement, specifically a kind of on-off system that is parallel with Passive components.
Background technology
As Fig. 1, conventional circuit breaker or switchgear have primary cut-out and low-voltage circuit breaker usually, and isolating switch or the switchgear related for the utility model all belong to low-voltage circuit breaker.Traditional low-voltage circuit breaker inside between end of incoming cables 1 and leading-out terminal 2 without any Passive components in parallel, when isolating switch or switchgear pass, in the situation that civil power E is arranged, on circuit without any current signal, the signal that detects electric current can't be provided for the consumer on the loop, therefore can't judge when isolating switch or switchgear shutoff, whether have civil power to exist before the inlet wire point of device.
Summary of the invention
The utility model purpose is to provide a kind of on-off system that is parallel with Passive components, a Passive components device in parallel between the end of incoming cables of low-voltage circuit breaker or switchgear and leading-out terminal, be used in the situation that civil power is arranged, when low-voltage circuit breaker or switch turn-off, produce trickle current signal in the loop.
The technical solution of the utility model is:
A kind of on-off system that is parallel with Passive components is characterized in that comprising Passive components and on-off system (S1), and described Passive components is connected in parallel between the end of incoming cables (1) and leading-out terminal (2) of on-off system (S1).Isolating switch or the switchgear of the utility model high voltage bearing Passive components in parallel between end of incoming cables and leading-out terminal, it comprises a low-voltage circuit breaker or switchgear and a high voltage bearing Passive components.The characteristics of this circuit are to have under civil power, and when low-voltage circuit breaker or switchgear shutoff, civil power produces trickle current signal by Passive components.
Described Passive components is high voltage bearing Passive components.
Described on-off system (S1) is low-voltage circuit breaker device or switchgear.
A Passive components device in parallel on the inlet wire point of isolating switch or switch and outlet point.When civil power exists, when if the isolating switch of this moment or switch disconnect, civil power can produce minute current during by the Passive components device on the line, thereby detection signal is provided for the rear end power device, when tiny electric current existed, proof had civil power, when civil power disconnects, flow through the Passive components device without any electric current, can't detect current signal with electric lighting device and illustrate there is no civil power.
The Passive components device is connected in parallel on isolating switch or switch, and when isolating switch or switch disconnected, line voltage was added on the Passive components device, produces the effect of minute current in the line loop.
When isolating switch or switchgear disconnected, the electrical network loop still had minute current to pass through, this moment the power device sensed current signal, when device detected signal, proof had civil power; When device did not detect signal, proof did not have civil power.
The beneficial effects of the utility model:
The on-off system that is parallel with Passive components of the present utility model, when having civil power and low-voltage circuit breaker or switchgear to disconnect, the Passive components device produces trickle current signal, when consumer detects when the device shutoff still has current signal, judge that electrical network has civil power existence before device inlet wire point, when consumer can't detect current signal in the loop, judge that electrical network exists without civil power before device inlet wire point.Strengthened the continuity of electricity consumption, simple in structure, be convenient to installation and maintenance, can be applicable to various electricity consumption occasions.
Description of drawings
Fig. 1 is traditional isolating switch or switchgear connection layout.
Fig. 2 be the utility model embodiment one use the connection diagram of the on-off system that is parallel with Passive components of release unit.
Fig. 3 be the utility model embodiment two use the connection diagram of the on-off system that is parallel with Passive components of switchgear.
Embodiment
, usually directly traditional isolating switch or switchgear are connected serially in circuit, directly control consumer 1, consumer 2 ... consumer N opening or closing, connected mode as shown in Figure 1.
And line connection of the present utility model such as Fig. 2 are shown in Figure 3.
Embodiment one.
As Fig. 2, it is high voltage bearing Passive components in parallel on position between the end of incoming cables 1 of conventional apparatus and leading-out terminal 2.Under this Passive components effect, on-off system S1 is release unit.
Embodiment two.
As Fig. 3, it is high voltage bearing Passive components in parallel on position between the end of incoming cables 1 of conventional apparatus and leading-out terminal 2.Under this Passive components effect, on-off system S1 is switchgear.
When civil power E has electricity, if this moment, on-off system S1 was closed, normal consumer 1, consumer 2 are given in civil power E conducting ... consumer N power supply is when on-off system S1 disconnects, this moment, consumer quit work, but this moment, civil power E was through Passive components, still consisted of on the line the loop conducting, under the Passive components dress is used, still have Weak current I to flow through consumer on circuit, for consumer provides current signal.In the situation that on-off system S1 closes electricity, when current signal I still being detected, can judge that electrical network E has civil power when consumer, when can't detect current signal I, prove that electrical network E is without civil power.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; various modification and improvement that in this area, common engineering technical personnel make the technical solution of the utility model; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection all is documented in claims.
