高压脉冲轨道电路源自法国，由发送设备、接收设备、电缆和扼流变压器或轨道变压器组成，主要分为差动继电器型和电子接收器型两种类型。该制式具有能击穿钢轨锈层、有利于列车分路的独特优势。自1984年通过原铁道部技术鉴定后，在我国站内分路不良区段开始使用。
目前该产品的行业标准《TJ/DW146-2012不对称高压脉冲轨道电路暂行技术条件》中规定，在0.6Ω·km的道床条件下，轨道电路的极限传输长度为900米。而现有的高压脉冲轨道电路结构，在面临长度接近900米的长区段传输时，会遇到传输长度和断轨检查功能不能兼顾的矛盾。现有的高压脉冲轨道电路无法检查该长区段中是否出现钢轨断轨的情况，这可能造成列车脱轨等事故，存在安全隐患。

附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请中记载的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。
图1为本申请提供的高压脉冲电路系统实施例一的结构示意图；
图2为本申请提供的高压脉冲电路系统实施例二的结构示意图。
具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在介绍本申请的具体实施方式之前，首先介绍与本申请的具体实施方式相关的多个技术术语。
高压脉冲轨道电路：即不对称高压脉冲轨道电路，通过产生正负不对称的高压脉冲来击穿钢轨的锈层，解决站内轨道电路的分路不良问题，用来检查轨道的空闲或占用。
断轨检查：是指在钢轨发生电气断离(列车占用、钢轨断裂或移除等)时，轨道电路能够显示为列车占用状态，是保证行车安全的功能之一。
实施例一：
参见图1，该图为本申请提供的高压脉冲轨道电路系统实施例一的结构示意图。
本实施例提供的高压脉冲轨道电路系统，包括：钢轨300、发送模块100、第一接收模块201和第二接收模块202。
所述发送模块100、所述第一接收模块201和所述第二接收模块202均与所述钢轨300连接，所述第一接收模块201和所述第二接收模块202分别位于所述钢轨300的两端，所述发送模块100位于所述第一接收模块201和所述第二接收模块202的中间。
可以理解的是，铁路轨道均为两条并行的钢轨组成，每条钢轨均被截断为不同的区段。实际应用中，每个区段的轨道上均设置有一个高压脉冲轨道电路系统来检查该区段内的钢轨是否发生电气断离。
基于此，为了检测出某一区段内的轨道是否发生电气断离，发送模块100、第一接收模块201和第二接收模块202需分别连接该区段内的两条钢轨300。
还需说明的是，为了防止每区段钢轨间的信号干扰，两个相邻的区段之间需在钢轨之间设置绝缘设施。即，所述钢轨300的两端均设置有绝缘节301，以防止与其相邻的两段钢轨上的信号对其检测结果的干扰。
所述发送模块100用于发送高压脉冲信号至所述第一接收模块201和所述第二接收模块202。
发送模块100发送的高压脉冲信号沿钢轨300向钢轨300的两端传输。当第一接收模块201接收到所述高压脉冲信号时，则说明其与发送模块100间的钢轨没有列车占用，也没有出现钢轨断裂或移除等情况；反之，当第一接收模块201未接收到所述高压脉冲信号时，则说明其与发送模块100间的钢轨有列车占用，或出现钢轨断裂或移除等情况。同理，当第二接收模块202接收到所述高压脉冲信号时，则说明其与发送模块100间的钢轨没有列车占用，也没有出现钢轨断裂或移除等情况；反之，当第二接收模块202未接收到所述高压脉冲信号时，则说明其与发送模块100间的钢轨有列车占用，或出现钢轨断裂或移除等情况。
可以理解的是，将第一接收模块201和第二接收模块202分别设置在钢轨300的两个顶端，就能保证检测到整段钢轨300的电气断离情况，保证行车安 全。
简单的说，就是通过两个接收模块，即第一接收模块201和第二接收模块202，分别检测发送模块100两侧钢轨的电气断离情况。这样，不仅减小了发送模块和接收模块间的距离，轨面电压大幅升高，提高了钢轨锈层击穿能力，还可保证在极限传输长度范围内的断轨检查功能，提升了列车运行的安全性。
在传输的过程中，高压脉冲信号受环境以及钢轨状态等因素的影响会有一定的衰减，如果第一接收模块201以及第二接收模块202与发送模块100之间的距离过远，就会导致第一接收模块201和第二接收模块202无法接收到该高压脉冲信号，影响对列车的调度以及对断轨的检查。
在本实施例优选的实施方案中，考虑到环境因素对钢轨300上传输条件的影响，所述钢轨300的长度应该小于或等于1200米。
可以理解的是，将发送模块100设置在第一接收模块201和第二接收模块202的正中间时，高压脉冲信号向两端传输的平均效果最好，即|L1-L2|≤100m，其中，L1为发送模块100与第二接收模块202之间的距离，L2为发送模块100与第二接收模块202之间的距离。然而，在实际铺设时，考虑到现场实际安装位置的偏差以及现有已铺设完成的铁路轨道中每段钢轨的长度，在|L1-L2|≤100m的情况下，就能够保证在不切断钢轨的情况下，检测出整段钢轨300的电气断离情况，节约了施工所需的人力物力，减少了所需的设备数量和电缆长度，节约了成本。
一般来说，当发送模块与接收模块的间隔超过600米时，高压脉冲信号在钢轨上的衰减会影响到接收模块对发送模块发出的高压脉冲信号的检测，影响对电气断离的判断。因此，为保证高压脉冲信号的传输质量，发送模块100与第一接收模块201之间的距离应小于或等于600米，发送模块100与第二接收模块202之间的距离小于或等于600米。
本申请实施例提供的高压脉冲电路系统，在每段钢轨的两端各设置一个接收模块，即第一接收模块和第二接收模块，并在钢轨的中间设置一个发送模块。发送模块用于将高压脉冲信号发送至钢轨，第一接收模块和第二接收模块通过接收高压脉冲信号，来检测其与发送模块之间的区间内的钢轨上是否有列车占用以及该区间内的钢轨是否出现断轨的情况。本申请实施例提供 的高压脉冲电路系统，减小了发送模块和接收模块间的距离，轨面电压大幅升高，提高了钢轨锈层击穿能力，并且在高压脉冲电路的极限传输长度范围内仍然能够实现对断轨情况的监测，大大提升了列车运行的安全性，节约了设备和成本。
实施例二：
参见图2，该图为本申请提供的高压脉冲轨道电路系统实施例二的结构示意图。相较于图1，本实施例提供了一种更加具体的高压脉冲轨道电路系统。

所述第一变压器101的第一绕组经电缆或者第一电阻R1连接所述发送设备102，所述第一变压器101的第二绕组连接所述钢轨300；
所述第一变压器101，用于根据所述发送设备102发送的脉冲信号生成所述高压脉冲信号，并将所述高压脉冲信号发送至所述钢轨300。
