Abstract
The utility model provides a pneumatic eight-way load tester. Two groups of interfaces respectively connected with two power supplies to be tested are arranged outside a case. A circuit inside the case consists of an automatic Pin releasing module, an automatic switching module and a load control circuit module. The automatic Pin releasing module consists of an air cylinder, a connecting bar, a switch control circuit and a plurality of eight-way testing interface boards. The piston rod of the air cylinder is connected with the connecting rod. The connecting rod is connected with two eight-way testing interface boards, which are respectively connected with the switch control circuit. The automatic switching module consists of two relay control circuits which provide power supply for the eight-way testing interface board. The load control circuit module for providing alternating-current input voltage, current and sequence control is connected with power supply to be tested. The pneumatic eight-way load tester has the advantages of reasonable design, simple operation, safety and reliability, thus being worth spreading and application.
Description
1, technical field
The utility model relates to a kind of power supply test equipment, specifically a kind of pneumatic type 8 road load testing instruments.
2, background technology
At present, carry out load testing and adopt artificial manual mode to carry out usually, not only efficient is low, also loses efficacy because of the man-made fault in the test process causes detecting easily.
How to improve the quality that research and development and IQC judge that power supply product detects, especially avoid the IQC related personnel damage that human factor causes power supply when detecting power supply, improve the ease for use when detecting, reliability, degree of accuracy become the important technological problems that product detects.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of automatic switchover power supply to be detected, pneumatic type 8 road load testing instruments of intelligent fast transition.
The technical solution of the utility model realizes in the following manner, pneumatic type 8 road load testing instruments, be outside equipped with two groups of interfaces that connect two power supplys to be measured at housing, circuit is formed by taking off Pin module, automatic switchover module and load control circuit module automatically in the housing.Automatically take off the Pin module and be made up of cylinder, connecting link, ON-OFF control circuit, the 8 drive tests oralia of trying, the piston rod of cylinder connects connecting link, and connecting link connects two 8 drive tests oralia of trying, and the 8 drive tests oralia of trying connects ON-OFF control circuit respectively.The automatic switchover module is made up of two groups of bang-bang circuits that provide 8 drive tests to try the oralia power supply.Ac input voltage is provided, and the load control circuit module of electric current and sequential control connects power supply to be measured.
The utility model has the advantages that:
1, ease for use, reliability and the degree of accuracy of load detecting have been improved;
2, the robotization that power supply detects, intellectuality have been improved;
3, the detection of having avoided man-made fault to cause was lost efficacy, and the destruction that human factor causes power supply to be measured in the testing process.
4, description of drawings
Accompanying drawing 1 is the functional block diagram of pneumatic type 8 road load testing instruments.
Mark in the accompanying drawing is represented respectively: cylinder 1, connecting link 2, ON-OFF control circuit 3,8 drive tests try oralia 4, bang-bang circuit 5, load control circuit 6.
5, embodiment
Below in conjunction with accompanying drawing pneumatic type 8 road load testing instruments of the present utility model are done following detailed description the in detail.
As shown in Figure 1, pneumatic type of the present utility model 8 road load testing instrument both sides outside housing are provided with the interface that connects two power supplys to be measured, and circuit is formed by taking off Pin module, automatic switchover module and load control circuit module automatically in the housing.When one is waitd upon survey power supply detect finish after, this instrument can automatically switch to the detection to another power supply, effectively improves testing efficiency.
Automatically taking off the Pin module is made up of cylinder 1, connecting link 2, two groups of ON-OFF control circuit 3 and the two group of 8 drive test oralia 4 of trying.The piston rod of cylinder 1 connects connecting link 2, for connecting link 2 provides power drive.Connecting link 2 connects two 8 drive tests oralia 4 of trying.The 8 drive tests oralia 4 of trying connects ON-OFF control circuit 3 respectively.After having detected a power supply to be measured, take off the Pin module automatically under the driving of cylinder 1, automatically switch to detection to another power supply, reduced tester's labor intensity and the conserver power source plug time.Power supply is inserted in try output line part on the oralia 4 of 8 drive tests, breaks away from automatically, can avoid extracting the output line that damages power supply, cause power source performance bad because of human factor by ON-OFF control circuit 3.
The automatic switchover module provides the bang-bang circuit 5 of power supply to form by two groups to the 8 drive tests oralia 4 of trying.
The load control circuit module provides ac input voltage to power supply to be measured, electric current and sequential control.Load control circuit 6 connects power supply to be measured.
Pneumatic type 8 road load testing instruments design of the present utility model are reasonable, simple in structure, safe and reliable, easy to use, be easy to characteristics such as maintenance, thereby, have good value for applications.
