Abstract
The utility model provides a kind of hoisting crane Special polar low temperature checking system, power supply is connected main switching control by power light with run indicator, main switching control divides four part in parallel, Part I connection signal processing instrument meter apparatus, signal transacting meter system series connection extremely low temperature detecting sensor, Part II connection signal processing equipment mouth, signal processor unit mouth series connection control relay, Part III connects another from master cock, from master cock series connection buzzer phone, Part IV connects from master cock, from master cock series connection heating equipment, the circuit of last main switching control arranges total contactless switch.The extremely low temperature check implement of this patent, energy-conserving and environment-protective, detect automatically at low temperatures, automatic alarm, and when temperature is too low, automatically carry out heating operation, improve Electric Appliance Cabinet temperature, reduce energy dissipation, improve work efficiency.
Description
Technical field
The utility model relates to hoisting crane electrical equipment detection field, is specifically related to a kind of hoisting crane Special polar low temperature checking system.
Background technology
At present; low temperature often can be out in the cold to the damage of electric elements; although what have takes certain measure; but there is certain defect; such as: although installed heating equipment in Electric Appliance Cabinet, when temperature is increased to normal value, heating equipment can not be braked and quit work; can not report to the police, on the contrary can because temperature is too high generation accident.
Utility model content
The technical matters that the utility model solves there are provided the hoisting crane Special polar low temperature checking system of a kind of automatic detection extremely low temperature, automatic alarm, reduction energy consumption.
Based on above-mentioned purpose, the technical matters that the utility model solves realizes by the following technical solutions:
A kind of hoisting crane Special polar low temperature checking system, power supply is connected main switching control by power light with run indicator, main switching control divides four part in parallel, Part I connection signal processing instrument meter apparatus, signal transacting meter system series connection low temperature detecting sensor, Part II connection signal processing equipment mouth, signal processor unit mouth series connection control relay, Part III connects another from master cock, from master cock series connection buzzer phone, Part IV connects from master cock, from master cock series connection heating device, the circuit of last main switching control arranges total contactless switch.
Further, described low temperature detecting sensor is in parallel with control relay, buzzer phone and heating device.
The beneficial effects of the utility model are: the extremely low temperature check implement of this patent, and energy-conserving and environment-protective, detect automatically at low temperatures, automatic alarm, and when temperature is too low, automatically carry out heating operation, improve Electric Appliance Cabinet temperature, reduce energy dissipation, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is circuit theory schematic diagram of the present utility model;
Detailed description of the invention
Below by way of Figure of description, set forth the utility model further.
As Fig. 1 indicate, a kind of hoisting crane Special polar low temperature checking system, power supply 1 is connected main switching control 4 by power light 2 with run indicator 3, main switching control 4 point of four part in parallel, Part I connection signal processing instrument meter apparatus 5, signal transacting meter system 5 is connected low temperature detecting sensor 6, Part II connection signal processing equipment mouth 7, signal processor unit mouth 7 is connected control relay 8, Part III connects another from master cock 4, to connect buzzer phone 9 from master cock 4, Part IV connects from master cock 4, to connect heating device 10 from master cock 4, the circuit of last main switching control 4 arranges total contactless switch 11, described low temperature detecting sensor 6 and control relay 8, buzzer phone 9 and heating device 10 parallel connection.
Principle of work: low temperature detecting sensor 6 is placed in Electric Appliance Cabinet, when temperature reduction in Electric Appliance Cabinet, low temperature detecting sensor 6 will detect temperature signal, and by signal transmission to signal transacting meter system 5, when temperature reduction in Electric Appliance Cabinet is to setting value, signal transacting meter system 5 will send instruction, make the buzzer phone 9 be arranged in operator's compartment will send warning to operator, and disconnected working power, open heating equipment 10 processed simultaneously, carry out heating operation, when temperature is elevated to normal value, heating equipment 10 quits work, and system can be recovered automatically.
Preferred embodiment of the present utility model is only, not in order to limit the utility model above.All make within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
