Problems solved by technology

[0002] Due to the failure of the power supply line, the reclosing function in the protection device of the power supply unit can quickly close the switch to restore power supply after the instantaneous fault circuit breaker trips. However, some power-consuming equipment will stop running. If there is no equipment operator during non-production hours, the equipment will always be in a deactivated state, which will affect production or equipment.

Embodiment Construction

[0011] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0012] refer to figure 1 , the momentary power failure alarm of the present invention comprises: AC contactor KM1, sound and light alarm B and power supply D, wherein, power supply D is used for providing DC working voltage for sound and light alarm B, so sound and light alarm B is connected to In the power supply D; the normally open contact KM1-1 of the AC contactor KM1 is connected in series on this line.

[0013] As a preferred solution, refer to figure 1 , A switch KF is also installed on the line, and the switch KF is used to control the on-off of the line current.

[0014] In the present invention, the power supply D can be either a storage battery or a DC panel battery in the power distribution room. When the DC panel battery in the power distribution room is selected as the power supply D, not only the cost can be saved, but a...

Abstract

The invention discloses an instant outage alarm. The instant outage alarm is characterized in that an alternating current contactor KM1, an audible and visual alarm B and a power source D providing direct current working voltage for the audible and visual alarm B are included, the audible and visual alarm B is connected into the power source D, a normally open contact KM1-1 of the alternating current contactor KM1 is connected to the circuit in series, and a switch KF is further installed on the circuit. The instant outage alarm has the advantages that the instant outage alarm is easy to manufacture, low in cost, high in stability and convenient to install; when the instant outage (power supply is restored immediately after the instant outage, and the outage time is larger than or equal to 0.2 second) of a power grid is monitored, the alarm with power supplied by a storage battery gives out a signal, the alarming is stopped until a person comes to tour off the alarm ( restore monitoring) or the electricity of the storage battery is used up so that related personnel can conveniently find the outage in time, and thus corresponding measures can be taken in time.

Description

technical field [0001] The invention relates to an alarm, in particular to an instantaneous power failure alarm, which belongs to the technical field of electric power monitoring equipment. Background technique [0002] Due to the failure of the power supply line, the reclosing function in the protection device of the power supply unit can quickly close the switch to restore power supply after the instantaneous fault circuit breaker trips. However, some power-consuming equipment will stop running. If there is no equipment operator during non-production hours, the equipment will always be in a deactivated state, which will affect production or equipment. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a momentary power failure alarm which is stable, easy to install, and can send out an alarm signal in time after a momentary power failure occurs. [0004] In order to achieve the above...
