Abstract
The utility model provides a contact net has signal of pressure detection device, sensor among the the device puts up with isolator altogether to be installed at same height, the high -pressure side of sensor passes through cable junction with isolator's inlet wire end, the sensor low -pressure end links to each other with the contact net negative pole, the sensor signal end passes through the wire with electrified detector and links to each other, when the voltage of sensing isolator when the high -pressure side of sensor is greater than 600V, electrified monitor is transfered with the signal to the low -pressure end of sensor, electrified detector offered passive bus signal of one -level this moment, realize that the contact net has the pressure to obtain detecting. The beneficial effects are that when contact net voltage is greater than 600V, go up the one -level and can show that the contact net has the signal of pressure can think that the contact net did not cut off the power supply temporarily this moment, when contact net voltage is lighter than 600V, on -the -spot constructor accessible articulates mode such as ground wire and lays down contact net response and survival voltage. Increase the contact net have press behind the detection device can the effectual constructor of preventing get an electric shock and the mistake articulates injures and deaths and the equipment damage that ground wire etc. Brought.
Description
Technical field
The utility model relates to a kind of contact system pressure signal supervisory instrument.
Background technology
When subway contact system upkeep operation and special equipment run, contact system need be had a power failure, contact net operation personnel detect disconnector by disconnector in point position or background job personnel backstage and judge that contact has a power failure in point position, and now contact system circuit breaker is in a point position.If when contact system parallel switch is extremely closed, the contact system had a power failure is still charged, or when backstage detection signal is abnormal, contact system is also still charged.Now, there are major safety risks in operating personnel.For contact net operation personnel provide safer guarantee, contact system has pressure detecting device.
Summary of the invention
For unicity structural in prior art, the purpose of this utility model is to provide a kind of contact system pressure signal supervisory instrument, is beneficial to the safety improving subway contact system upkeep operation.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of contact system pressure signal supervisory instrument, the disconnector that this device is located in contact system side and operating mechanism case is installed side by side, wherein: in this device, be provided with sensor, hot detector, described sensor and disconnector altogether frame are arranged on sustained height, the high-pressure side of sensor is connected by cable with the end of incoming cables of disconnector, sensor low tension terminal is connected with contact system negative pole, sensor signal end is connected by wire with hot detector, when the high-pressure side of sensor (1) senses that the voltage of disconnector is greater than 600V, signal is passed to live monitoring device by the low tension terminal of sensor, now hot detector is supplied to upper class passive bus signal, realizing contact system has pressure to be detected.
Effect of the present utility model is when contact system voltage is greater than 600V, upper class can show contact system has pressure signal can think now contact system temporarily non-power-off, when contact system voltage is less than 600V, site operation personnel lay down contact system induction and residual voltage by modes such as hanging earthing conductors. and increase after contact system has pressure detecting device and can prevent workmen from getting an electric shock and the by mistake injures and deaths brought such as hanging earthing conductor and device damage by actv..Substantially increase the safety of contact net operation personnel and equipment.Contact system has pressure signal supervisory instrument can reflect contact net electrification situation in real time, and precision is high.

Detailed description of the invention
The structure structure of pressure signal supervisory instrument is had to be illustrated to contact system of the present utility model by reference to the accompanying drawings.
Contact system of the present utility model has pressure signal supervisory instrument structure to be, the disconnector 3 that this device is located in contact system side and operating mechanism case is installed side by side, sensor 1 is provided with in this device, hot detector 2, described sensor 1 and disconnector 3 altogether frame are arranged on sustained height, the high-pressure side of sensor 1 is connected by cable with the end of incoming cables of disconnector 3, sensor 1 low tension terminal is connected with contact system negative pole, sensor 1 signal end is connected by wire with hot detector 2, when the high-pressure side of sensor 1 senses that the voltage of disconnector 3 is greater than 600V, signal is passed to live monitoring device 2 by the low tension terminal of sensor 1, now hot detector 2 is supplied to upper class passive bus signal, realizing contact system has pressure to be detected.
Hot detector 2 can detect contact system voltage in real time and whether be greater than 600V, and contact system can be provided to have pressure signal
As shown in Figure 1, voltage sensor 1 and disconnector 3 altogether frame are installed and are installed on sustained height, and after installing, voltage sensor 1 high-pressure side is connected with disconnector 3 end of incoming cables, and voltage sensor 1 low tension terminal is connected with contact system negative pole.
Voltage sensor 1 signal end is connected with hot detector 2, and hot detector 2 provides contact system to have pressure passive bus signal.
When contact system voltage is greater than 600V, voltage sensor 1 sends signal to hot detector 2 by signal end after responding to, and the connection of hot detector 2 passive bus is contact system pressure signal.
