Abstract
The utility model relates to a zero line power-disconnection protector, which is particularly suitable for the automatic protection of the house household appliances. The protector is provided with an electromagnet [5] which is connected on the zero line of the user. A resistance R is connected in series between the zero line and the electromagnet [5]. The other end of the zero line is connected with the ground. A linkage switch [3] is connected in series between the zero line and the fire line of the user. When certain part of the power supply zero line is disconnected, the electromagnet [5] generates suction and the armature drives the linkage switch [3] to disconnect the main circuit, thus the household appliances [6] can be protected. The utility model has simple structure, is safe and reliable.
Description
The utility model relates to a kind of zero line and disconnects protector, uses when being specially adapted to automatic defend the dwelling household electrical appliance.
Present residential electric power, when the somewhere, common zero line upper end of current supply circuit disconnects suddenly, two or three following single-phase loops of breakpoint this moment also promptly form the supply power voltage that voltage is 380v, the household electrical appliance of rated voltage 220v are punctured or burn, and work the mischief.
The purpose of this utility model provides a kind of can cutting off the electricity supply by timely disjunction main circuit after zero line disconnects, avoid burning household electrical appliance, reliable in action, safe ready.
The utility model is achieved in that and is connected to an electromagnet on user's zero line, resistance R of one end serial connection, other end ground connection is being connected in series a linked switch on user's zero line and on the live wire, there is a spring linked switch upper end and fixes with housing, and there is an armature lower end.When the major loop zero line disconnects, produce voltage on user's zero line, make electromagnet produce suction, thereby make armature drive linked switch, with user's dump, thereby play the purpose of protecting household electrical appliance.
The utility model is simple in structure, reliable in action, and safe ready, flexible operation can play the effect of automatic protection household electrical appliance.
The utility model is provided by following examples:
Fig. 1 is a structure principle chart of the present utility model
Below in conjunction with accompanying drawing the utility model is described in detail:
It is to be connected to an electromagnet [5] on user's zero line that zero line disconnects protector, and string has a resistance R, other end ground connection between zero line and the electromagnet [5].A serial connection linked switch [3] on user's zero line and live wire, linked switch [3] upper end has a spring [2], spring [2] to be fixed on the protector housing [1], and there is an armature [4] lower end.When certain of power supply zero line disconnects; the zero line of rear end can form current circuit by resistance R, electromagnet [5], the earth point of zero line protector; electromagnet [5] produces suction; armature [4] action; drive linked switch [3]; disconnect main circuit rapidly, thereby household electrical appliance [6] are played a protective role.Do not disconnect when common zero line, power just often, zero line can not produce electric current, though electromagnet is connected on the loop, does not produce suction, keeps main circuit by spring [1] and connects.
Claims (3)
1, a kind of neutral line break protector; it is made up of electromagnet (5), resistance R, linked switch (3), armature (4), spring (5); it is characterized in that linked switch (3) is serially connected on the subscriber line circuit, electromagnet [5] circuit one end is connected on the zero line of user's power end other end ground connection.
2, neutral line break protector according to claim 1 is characterized in that linked switch (3) upper end is associated with a spring (5) and fixes in housing, and the other end is associated with an armature (4).
3, neutral line break protector according to claim 1 is characterized in that by electromagnet (5) resistance R of connecting between user's zero line.
