Description
Technical field
The utility model relates to the elevator safety protection checkout gear in a kind of control loop that is applied to elevator.
Background technology
Shown in accompanying drawing 1, existing elevator control loop comprises control loop main circuit breaker QRun, control loop transformer TR1, secondary circuit breaker Q 1, these several parts of Switching Power Supply G1.Wherein, the input of control loop main circuit breaker QRun is got phase line in three-phase electrical source of power and a neutral line (zero line) power supply as elevator control loop, and control loop transformer TR1, secondary circuit breaker Q 1, Switching Power Supply G1 are connected on the loop of output of control loop main circuit breaker QRun.
This elevator control loop, without between power supply and its, circuit controls transformer being set, is therefore saved cost.But in actual use, often there is control loop transformer and related device burnout phenomenon in this control loop, the main cause that occurs this problem is the also informal access of formal power supply of user while installing at the elevator initial stage, what site operation unit was used is construction temporary source, construction temporary source presses fluctuation larger because various live loads all access this power supply electrifying, and on site, there are multiple construction teams to connect construction with occur the unsettled situation of the neutral line (zero line) after temporary source through often, these situations can cause control loop power supply higher or on the low side, thereby cause related device in this control loop to damage.Specific as follows:
1, in the time that the primary voltage of three-phase electrical source of power is too high, owing to there is no over-pressure safety device in control loop, causes the input of control loop main circuit breaker QRun, the device overtension of outlet side, thereby cause the device failure in this loop;
2, in the time that the primary voltage of three-phase electrical source of power is normal, if on-the-spot because zero line is unsettled, while utilizing the other phase line of three-phase electrical source of power and the neutral line (zero line) as the power supply of equipment when there being other power consumption equipment, the input power that can cause control loop main circuit breaker QRun is AC380V left and right, due to the overtension of defeated people's side, cause the device failure in control loop main circuit breaker QRun outlet side loop;
3, in the time that the primary voltage of three-phase electrical source of power is too low; owing to there is no undervoltage protection device in control loop; cause the device long-term work of control loop main circuit breaker QRun outlet side at low-pressure state; some electrical load can not long-term work in low-voltage state, long-term work can cause device failure in low-voltage state.
Summary of the invention
The purpose of this utility model is to provide a kind ofly can avoid device in elevator control loop due to overvoltage, the under-voltage or unsettled elevator safety protection checkout gear damaging of zero line.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of elevator safety protection checkout gear, is arranged in elevator control loop, and described elevator control loop comprises control loop main circuit breaker, control loop transformer, secondary circuit breaker, Switching Power Supply, described elevator control loop is connected on the electric power loop of being drawn by phase line of three-phase electrical source of power and neutral line, described control loop main circuit breaker is arranged on described electric power loop, described control loop transformer, described secondary circuit breaker is connected in series mutually and is connected with described electric power loop, described Switching Power Supply is connected on described electric power loop, and described three-phase electrical source of power is positioned at input one side of described control loop main circuit breaker, described control loop transformer, described secondary circuit breaker, described Switching Power Supply is positioned at output one side of described control loop main circuit breaker, described elevator safety protection checkout gear comprises overvoltage and the under-voltage protection module of the break-make that can control described control loop main circuit breaker, the input of described overvoltage and under-voltage protection module is connected with the output of described control loop main circuit breaker, and the output of described overvoltage and under-voltage protection module is connected with described control loop main circuit breaker.
Because technique scheme is used; the utility model compared with prior art has following advantages: the utility model is set up in elevator control loop; though its cost is little; but can effectively carry out over voltage protection to the device in elevator control loop, solve the electric equipment causing due to on-the-spot voltage problem and damaged problem.
Brief description of the drawings
Accompanying drawing 1 is the principle schematic of existing elevator control loop.
