Description
Technical field
The present invention relates to the elevator safety in a kind of control loop applied to elevator to protect detection means.
Background technology
Referring to shown in accompanying drawing 1, existing elevator controlling loop includes control loop main circuit breaker QRun, control loop transformation
This several part of device TR1, secondary circuit breaker Q 1, Switching Power Supply G1.Wherein, control loop main circuit breaker QRun input takes three-phase to move
A phase line and a neutral conductor in power power supply（Zero line）As the power supply in elevator controlling loop, and control loop transformer
TR1, secondary circuit breaker Q 1, Switching Power Supply G1 are then connected on the loop of control loop main circuit breaker QRun output end.
Cost is relatively saved in this elevator controlling loop without setting circuit controls transformer between power supply and its.
But in actual use, often there is control loop transformer and related device burnout phenomenon in this control loop, go out
The main reason for this existing problem for elevator installation at initial stage when user formal power supply do not access formally also, site operation unit makes
It is construction temporary source, construction temporary source presses fluctuation larger because various live loads all access this power supply electrifying, and
There are multiple construction teams to connect after construction temporary source through often there is the neutral conductor on site（Zero line）Hanging situation, these situations
Control loop power supply can be caused higher or relatively low, so as to cause related device in this control loop to damage.It is specific as follows：
1st, when the primary voltage of three-phase electrical source of power is too high, due to there is no over-pressure safety device in control loop, cause
Control loop main circuit breaker QRun input, the device overtension of outlet side, so as to cause the device failure in this loop；
2nd, when the primary voltage of three-phase electrical source of power is normal, if scene is set because zero line is hanging when there is other electricity consumptions
Standby is the other phase line and the neutral conductor using three-phase electrical source of power（Zero line）During power supply as equipment, it can cause to control back
Road main circuit breaker QRun input power is AC380V or so, due to the overtension of defeated people side, causes the main open circuit of control loop
Device QRun exports the device failure of side loop；
3rd, when the primary voltage of three-phase electrical source of power is too low, due to there is no undervoltage protection device in control loop, cause
In low-pressure state, some electrical loads are unable to long-term work and existed for the device long-term work of control loop main circuit breaker QRun outlet sides
Low-voltage state, long-term work can cause device failure in low-voltage state.
The content of the invention
It is an object of the invention to provide a kind of device that can be avoided in elevator controlling loop due to over-pressed, under-voltage or zero line
Elevator safety that is hanging and damaging protects detection means.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of elevator safety protects detection means, is arranged in elevator controlling loop, described elevator controlling loop includes
Control loop main circuit breaker, control loop transformer, secondary breaker, Switching Power Supply；Described elevator controlling loop be connected to by
On the electric power loop that a piece phase line of three-phase electrical source of power and a neutral conductor are drawn, described control loop main circuit breaker is set
In on described electric power loop, described control loop transformer, described secondary breaker are mutually concatenated and returned with described power supply
Road is connected, and described Switching Power Supply is connected on described electric power loop, and described three-phase electrical source of power is positioned at described
The input side of control loop main circuit breaker, described control loop transformer, described secondary breaker, described switch electricity
Source is located at the output end side of described control loop main circuit breaker；Described elevator safety protection detection means includes controlling
The overvoltage of the break-make of the described control loop main circuit breaker of system and under-voltage protective module, described overvoltage and under-voltage protective module
Input is connected with the output end of described control loop main circuit breaker, the output end of described overvoltage and under-voltage protective module
It is connected with described control loop main circuit breaker.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：The present invention is set up in electricity
In terraced control loop, though its cost is small, over voltage protection effectively can be carried out to the device in elevator controlling loop, solved
Electrical equipment damages problem caused by the live voltage problem.
Brief description of the drawings
Accompanying drawing 1 is the principle schematic in existing elevator controlling loop.
Accompanying drawing 2 is the principle schematic using the elevator controlling loop of the present invention.
In the figures above：1st, overvoltage and under-voltage protective module.
Embodiment
The invention will be further described for shown embodiment below in conjunction with the accompanying drawings.
Embodiment one：Referring to shown in accompanying drawing 2, elevator controlling loop includes control loop main circuit breaker QRun, control loop
Transformer TR1, secondary circuit breaker Q 1, Switching Power Supply G1.The elevator controlling loop is connected to a phase line by three-phase electrical source of power
On the electric power loop drawn with a neutral conductor, control loop main circuit breaker QRun is arranged on electric power loop, two input
End is connected with a phase line of three-phase electrical source of power and a neutral conductor, and output end then draws two electric power loops, and
