背景技术 Background technique
目前三级站的油系统往往是通过手动控制，而实际电站运行过程中需要频繁地手动控制加油系统的启动和停止，油泵启动频繁，运行16分钟，停止12分钟；并且还存在着安全隐患，因此必须有人定点值守。 At present, the oil system of the tertiary station is often controlled manually, but in the actual operation of the power station, it is necessary to manually control the start and stop of the oil system frequently. The oil pump starts frequently, runs for 16 minutes, and stops for 12 minutes; and there are still potential safety hazards. Therefore, someone must be on duty.
变电站循环润滑系统是电机机组安全运行的重要环节，它主要用于高速转润滑系统中，对系统起到润滑保护作用。如果润滑系统出现的故障，往往会造成机组的事故停机，更甚者导致烧坏机组，从而使整个电站瘫痪，造成企业的损失及不良的社会影响。 The circulating lubrication system of the substation is an important part of the safe operation of the motor unit. It is mainly used in the high-speed transmission lubrication system to lubricate and protect the system. If the lubrication system fails, it will often cause the unit to shut down in an accident, or even cause the unit to burn out, thereby paralyzing the entire power station, causing losses to the enterprise and adverse social impacts.

Therefore, in order to meet the oil consumption requirements of multiple units, the oil pump with the largest amount is often selected. However, when the actual power station is running, one or two units often run, all The probability of running the installed machines at the same time is low, resulting in excessive capacity of the oil pump and wasting energy.
因此需要一种能实现润滑油系统自动控制、无人值守的装置。 Therefore need a kind of device that can realize lubricating oil system automatic control, unattended.

3个油泵能通过现场主油箱发出的压力信号进行自动切换，保证供油压力的正常；油站现场在主油箱和高位油箱分别安装具有高低位开关信号输出的液位控制器，参与整个供油系统的控制。其实现的控制方式如下：在主油箱安装的液位控制器具有低液位两级信号输出。第一级低液位信号输出的位置高于第二级低液位信号输出的位置。当第一级低液位信号输出时，控制柜发出主油箱液位低的报警信号（灯光，蜂鸣信号），此时油泵继续工作。当第二级低液位信号输出时，正在工作的油泵停止工作。当主油箱的液位到达液位控制器高液位信号输出的位置时，同样会发出主油箱液位高的报警信号。高位油箱安装的液位控制器也必须具有低液位两级信号输出。当第一级低液位信号输出时，现场控制柜发出高位油箱液位低的报警信号。当第二级低液位信号输出时，控制柜自动启动现场油泵，使主油箱的润滑油流入高位油箱。当高位油箱的液位达到液位控制器高液位信号输出的位置时，控制柜会发出高位油箱液位高的报警信号，同时正在工作的所有油泵停止工作。 The 3 oil pumps can switch automatically through the pressure signal sent by the main oil tank on site to ensure the normal oil supply pressure; the oil station site installs liquid level controllers with high and low level switch signal output on the main oil tank and high level oil tank respectively to participate in the entire oil supply System control. The control method is as follows: the liquid level controller installed in the main oil tank has two-stage signal output for low liquid level. The output position of the first low liquid level signal is higher than the output position of the second low liquid level signal. When the first stage low liquid level signal is output, the control cabinet sends out an alarm signal (light, buzzer signal) for the low liquid level of the main fuel tank, and the oil pump continues to work at this time. When the second stage low liquid level signal is output, the working oil pump stops working. When the liquid level of the main oil tank reaches the output position of the high liquid level signal of the liquid level controller, an alarm signal of the high liquid level of the main oil tank will also be sent. The liquid level controller installed in the high oil tank must also have a low liquid level two-stage signal output. When the first level low liquid level signal is output, the field control cabinet sends out an alarm signal of low liquid level in the high level fuel tank. When the second-level low liquid level signal is output, the control cabinet automatically starts the on-site oil pump, so that the lubricating oil in the main oil tank flows into the high-level oil tank. When the liquid level of the high level fuel tank reaches the output position of the high liquid level signal of the liquid level controller, the control cabinet will send out an alarm signal of high liquid level of the high level fuel tank, and all the working oil pumps will stop working at the same time.
本控制系统用于3个油泵独立运行，即同一时间只有一个油泵投入工作。正常情况下，第一油泵投入运行，当发生突然事故导致第一油泵停机时，第二油泵自动投入运行，当第二油泵发生故障停运时第三泵立即自动投入运行。如果第一油泵故障消除后控制系统则自动切换到第一油泵运行，第二油泵或第三油泵将停止运行。 This control system is used for independent operation of three oil pumps, that is, only one oil pump is put into work at the same time. Under normal circumstances, the first oil pump is put into operation. When a sudden accident causes the first oil pump to stop, the second oil pump is automatically put into operation. When the second oil pump fails and stops, the third pump is automatically put into operation immediately. If the failure of the first oil pump is eliminated, the control system will automatically switch to the operation of the first oil pump, and the second oil pump or the third oil pump will stop running.
最后说明的是，以上实施例仅用以说明本实用新型的技术方案而非限制，尽管通过参照本实用新型的优选实施例已经对本实用新型进行了描述，但本领域的普通技术人员应当理解，可以在形式上和细节上对其作出各种各样的改变，而不偏离所附权利要求书所限定的本实用新型的精神和范围。 Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described with reference to the preferred embodiment of the utility model, those of ordinary skill in the art should understand that, Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
