Description
Technical field
The present invention relates to person in electronics, be specifically related to the seismaesthesia pick-up unit for switch cubicle.
Background technology
In recent years, along with country greatly develops, western great development etc. is greatly developed, the use of electrical equipment is at High aititude, and seismic region gets more and more, and switchgear is shockproof, shockproof requirements also can not be ignored, if switchgear does not have tripping operation to cut off the electricity supply in strenuous vibration, personal injury of shocking by electricity may be there is, cause unnecessary loss.
Summary of the invention
The object of this invention is to provide the seismaesthesia pick-up unit for switch cubicle, it has, and principle is simple, easy for installation, the feature such as to cut off the electricity supply in time when strenuous vibration.
In order to solve the problem existing for background technology, we are by the following technical solutions: it comprises shock sensor 1, charge amplifier 2, A/D digital to analog converter 3, frequency tester 4, single-chip microcomputer 5, I/O delivery outlet 6 and relay delivery outlet 7 are installed above single-chip microcomputer, shock sensor 1 is connected with charge amplifier 2, A/D digital to analog converter 3 is connected with charge amplifier 2, single-chip microcomputer 5 respectively with frequency tester 4, and charge amplifier 2 is connected with I/O delivery outlet 6 respectively with frequency tester 4.
The advantage that the present invention has: switchgear does not have tripping operation to cut off the electricity supply in strenuous vibration; personal injury of shocking by electricity may be there is; cause unnecessary loss; the application is arranged in switchgear for this type of situation in the region that geographical environment is more bad; can effectively under the violent shake such as monitor earthquake; speed can be opened cut off the electricity supply, protection subordinate equipment.
Accompanying drawing illustrates:
Fig. 1 is structure principle chart of the present invention.
Embodiment
With reference to Fig. 1, the present invention is arranged on bottom the cabinet that opens the light, detect the vibrations from ground, 1. these mechanical variables are converted into electric signal according to different frequency sensors, 2. signal is amplified and normalization process by charge amplifier again, the voltage signal simultaneously exported respectively to digital to analog converter 3. with frequency tester 7., digital to analog converter is the signal voltage signal of analog quantity being converted to digital quantity, 4. receiving and analyzing signal is carried out to give next stage single-chip microcomputer, the size of vibrations that simultaneously ground spreads out of is reacted by frequency, the frequency size that 7. frequency tester receives signal is analyzed, result is transferred to single-chip microcomputer 4. chip, the input/output port be connected with single-chip microcomputer 5. signal is fed back to again charge amplifier 2. with frequency tester 7. in, after measuring the frequency of vibration source, 4. single-chip microcomputer provides instruction and whether reaches strenuous vibration index, whether sends alerting signal, the equipment such as the isolating switch of step switch equipment, and multiloop is reported to the police and exported to operator on duty and remind simultaneously.
The present invention be directed to installation of electrical equipment at bad environments and normal easily there are vibrations place and the device newly innovated, this equipment is arranged on the bottom of switchgear, the variable of environment effectively can be detected, mechanical variables dress is changed to a kind of device of digital quantity, output alarm signal simultaneously, be connected in the electric operation loop of switch disconnector, in order to tripping operation, excision power supply.
