Abstract

The utility model discloses an error-proof electromagnetic lock device, which comprises a knife switch auxiliary circuit and a power off error-proof circuit. The knife switch auxiliary circuit comprises auxiliary knife switches, an electronic lock coil and a normally-closed contact of an intermediate relay which are connected with a UPS (Uninterrupted Power supply) in series; the power off error-proof circuit comprises an intermediate relay and auxiliary knife switches connected with a PT power supply in series; and a quick-break switch is arranged in each of the knife switch auxiliary circuit and the power off error-proof circuit. The error-proof electromagnetic lock device of the utility model is simple in structure and strong in practicality, and can effectively avoid misoperation accident caused by that inductive voltage electrifies lines.

Description

Anti-error Electromalgnetic locking mechanism
Technical field
The utility model relates to a kind of anti-error Electromalgnetic locking mechanism.
Background technology
In field of power, the operator on duty is to joint using before wherein a dead line is done safety measure of circuit, when doing safety measure because of electroscope moment damage or to dead line, electroscope can send sound when common electroscope had really had a power failure at the identification circuit, and operating personnel can't judge whether circuit is charged; For the high-tension cable of 110KV, only at mains side the ground connection disconnecting link is installed, often because induced voltage causes circuit charged, bring the Personal Risk to the staff after the power failure.
Summary of the invention
The utility model is a kind of anti-error Electromalgnetic locking mechanism, and it can overcome because of electroscope moment damages or when dead line done safety measure, common electroscope identify circuit when really having had a power failure electroscope can send sound, operating personnel can't judge whether circuit charged; Also can overcome because induced voltage causes circuit charged, bring the Personal Risk to the staff.
For achieving the above object, this is practical to provide a kind of anti-error Electromalgnetic locking mechanism, and it comprises disconnecting link work auxiliary circuit and the anti-error circuit of outage; Described disconnecting link work auxiliary circuit comprises disconnecting link auxiliary switch, electronic lock coil and the auxiliary relay normally-closed contact that is connected in series with ups power; The anti-error circuit of described outage comprises auxiliary relay and the disconnecting link auxiliary switch that is connected in series with the PT power supply.
In described disconnecting link work auxiliary circuit and the anti-error circuit of outage, be equipped with quick-break switch.
Adopt the utility model of technique scheme that following advantage is arranged: to overcome because of electroscope moment and damage or when dead line done safety measure, electroscope can send sound when common electroscope had really had a power failure at the identification circuit, and operating personnel can't judge whether circuit is charged; Also can overcome because induced voltage causes circuit charged, bring the Personal Risk to the staff; Simple in structure, practical, production cost is low, is convenient to implement.
Description of drawings
Fig. 1 is disconnecting link work auxiliary circuit figure of the present utility model.
Fig. 2 is the anti-error circuit diagram of outage of the present utility model.
Embodiment
Below in conjunction with accompanying drawing this specific purpose tool is further described.
As shown in Figure 1 and Figure 2, the utility model comprises disconnecting link work auxiliary circuit and the anti-error circuit of outage; Described disconnecting link work auxiliary circuit comprises the disconnecting link auxiliary switch K1 that is connected in series with ups power, K2, electronic lock coil YL and auxiliary relay normally-closed contact KA-1; The anti-error circuit of described outage comprises auxiliary relay KA and the disconnecting link auxiliary switch K1 that is connected in series with the PT power supply, K2; In described disconnecting link work auxiliary circuit and the anti-error circuit of outage, be equipped with quick-break switch.
Operating principle of the present utility model:
1, just often first disconnecting link in line side is in running status, and its disconnecting link auxiliary switch K1, cuts off ups power, line side A phase PT voltage K2, and electronic lock coil YL does not have voltage, and electromagnetic lock can not be opened.
2, out of service when certain line switching, remove standby, when line side first disconnecting link draws back, its disconnecting link auxiliary switch K1, the K2 contact is connected, and auxiliary relay KA coil is charged, and its normally closed contact disconnects, electromagnetic lock coil YL is not charged, proves that certain circuit is charged, and ground, line side disconnecting link does not close.
3, when certain line outage, auxiliary relay KA coil losing electricity, its normally closed contact closure, YL is charged for the electromagnetic lock coil, can open electromagnetic lock, and certain ground, line side disconnecting link just can close, and prevents from closing the ground disconnecting link by mistake.

Claims (2)
