Embodiment Construction

[0027] The applicant's design original intention of the present invention is as follows:

[0028] The hidden fault inspection of the electrical control circuit has always been the most difficult point of electrical inspection. Due to the sporadic and instantaneous characteristics of the hidden fault, it is extremely difficult to capture the specific action of the hidden fault. That's right, reboot the device and it should work fine again. For such hidden faults related to important equipment, the maintenance personnel spend a lot of time and energy, often staying at the equipment operation site for several days and nights, staring at it without relaxing for a moment, but the equipment does not appear the previous unprovoked linkage startup phenomenon , so that maintenance personnel physically and mentally exhausted. And if the hidden fault is not found and eliminated in time, it will bury a great safety hazard for the next normal operation of the unit. The applicant of the p...

Abstract

The invention relates to a device for quickly displaying and discriminating hidden faults, which belongs to the technical field of electrical control maintenance. Including the secondary wiring circuit and display / discrimination component of each main oil pump control circuit; the display / discrimination component installed in the secondary wiring circuit of each main oil pump control circuit consists of a local start relay JRA, an oil pump outlet low oil pressure relay JRB, and a latch chip and the display circuit; the local start button and the oil pressure switch in the secondary wiring circuit are respectively provided with the local start relay JRA, and the low oil pressure relay JRB at the outlet of the oil pump; the branch circuit of the control power switch PB1 passes through the normally open contact of the local start relay Replacement of JRA1.1, main oil pump outlet low oil pressure switch PSC6 branch through the normally open contact JRB1.1 of the oil pump outlet low oil pressure relay; make up for the loopholes in the electronic control system supervision, the circuit structure is simple and easy to manufacture, real-time and fast display to identify recessive Fault location, to avoid hidden faults, easy maintenance and repair.

Description

technical field [0001] The invention relates to a device for quickly displaying and discriminating hidden faults, which belongs to the technical field of electrical control maintenance. Background technique [0002] The power generation system of a thermal power plant cannot do without an oil pump. In order to ensure the normal operation of the generator set and uninterrupted output of electric energy, two main oil pumps are usually installed in the generator set as backup for each other. When one of the main oil pumps in normal operation stops running, the electronic control system and computer will automatically start in chain Another main oil pump is put into use, and the other standby main oil pump will not start when one main oil pump is operating normally. However, in the actual power generation process, when the 2# main oil pump is running normally, the 1# main oil pump suddenly starts to run. Since the control circuit of the main oil pump cannot be checked during th...
