Description
技术领域technical field
本发明涉及一种航天用低频电缆网导通和绝缘自动化测试方法，应用于通信卫星低频电缆网导通和绝缘自动化测试中。The invention relates to an automatic test method for the conduction and insulation of a low-frequency cable network used in aerospace, which is applied to the automatic test for the conduction and insulation of the low-frequency cable network of communication satellites.
背景技术Background technique
低频电缆网在整星敷设安装绑扎后，需要对低频电缆网导通和绝缘特性进行测试。验证电缆网接点的正确性，避免出现短路或者断路，导致星上设备烧毁或者安全事故。After the low-frequency cable network is laid, installed and bound throughout the star, it is necessary to test the conduction and insulation characteristics of the low-frequency cable network. Verify the correctness of the cable network connection to avoid short circuit or open circuit, which may cause burnout of on-board equipment or safety accidents.
目前通信卫星低频电缆网在星上进行导通测试时，将两条线插入到两个电连接器的相应的点上，中间串入蜂鸣器，当蜂鸣器响时说明电连接器上的点导通，采用这种方式只能给出定性的结果，没法给出电缆导通时的实际电阻值。在绝缘测试时，用绝缘表将星上一个电连接器每一点和其他所有点依次进行手动测试，采用该种方式需要占用大量的时间和人力，同时长时间的单调重复工作，极容易出现漏点的情况。At present, when the communication satellite low-frequency cable network is conducting a conduction test on the satellite, insert two wires into the corresponding points of the two electrical connectors, and insert a buzzer in the middle. When the buzzer sounds, it means that the electrical connector is connected. This method can only give qualitative results, but cannot give the actual resistance value when the cable is turned on. During the insulation test, use an insulation meter to manually test each point of an electrical connector on the star and all other points in sequence. This method requires a lot of time and manpower. At the same time, long-term monotonous repetitive work is very prone to leakage point situation.

The current between each core wire and the remaining core wires of the tested cable is measured one by one to obtain the insulation condition of the tested cable.
具体地，以测试分支A电连接器第6个接点的绝缘电阻为例，如图3所示，恒压源模块的正端VIH连接到继电器JV1的一端，继电器JV1的另一端连接至继电器JA6的一端，继电器JA6的另一端分别连接到继电器JB6和转接电缆A上，转接电缆A的另一端连接到被测电缆分支A电连接器上。恒压源模块的负端SVL连接到继电器JS1的一端，继电器JS1的另一端分别连接到继电器JB1～JB5和继电器JB7～JB100的一端，继电器JB1～JB5和JB7～JB100的另一端分别连接到转接电缆A上。Specifically, taking the insulation resistance of the sixth contact of the electrical connector of the test branch A as an example, as shown in Figure 3, the positive terminal VIH of the constant voltage source module is connected to one end of the relay JV1, and the other end of the relay JV1 is connected to the relay JA6 The other end of the relay JA6 is respectively connected to the relay JB6 and the transfer cable A, and the other end of the transfer cable A is connected to the electric connector of the branch A of the tested cable. The negative terminal SVL of the constant voltage source module is connected to one end of relay JS1, the other end of relay JS1 is respectively connected to one end of relays JB1~JB5 and relays JB7~JB100, and the other end of relays JB1~JB5 and JB7~JB100 is connected to relay Connect to cable A.
绝缘电阻测试时，控制继电器JA6和JV1闭合，将被测电缆分支A电连接器的第6个接点连接到恒压源模块的正端VIH(图3中粗实线所示)。控制继电器JB1～JB5、JB7～JB100和JS1闭合，将被测电缆分支A电连接器的其他芯线连接至恒压源模块的负端SVL(图3中虚线所示)。采集此通路上的电流，计算绝缘电阻,并逐一测被测电缆分支A其余的每条芯线与其余芯线之间的电流，计算相应的每个绝缘电阻,最终判断被测电缆的绝缘情况。During the insulation resistance test, the control relays JA6 and JV1 are closed, and the sixth contact of the electrical connector of the branch A of the tested cable is connected to the positive terminal VIH of the constant voltage source module (shown by the thick solid line in Figure 3). The control relays JB1~JB5, JB7~JB100 and JS1 are closed, and connect the other core wires of the electrical connector of branch A of the tested cable to the negative terminal SVL of the constant voltage source module (shown by the dotted line in Figure 3). Collect the current on this path, calculate the insulation resistance, and measure the current between each core wire and the remaining core wires of the cable branch A under test one by one, calculate each corresponding insulation resistance, and finally judge the insulation condition of the cable under test .
上述中所有继电器采用固态继电器，以实现频繁通断切换。All of the above relays use solid state relays to achieve frequent on-off switching.
