Abstract

This utility model discloses a failure locking alarming apparatus for a vacuum circuit breaker, which comprises a vacuum pressure sensor which is provided within a vacuum arc-extinguishing chamber of a vacuum switch. The vacuum pressure sensor converts vacuum pressure signals in the vacuum arc-extinguishing chamber to ion flow signals which access a signal input terminal of a vacuum tester. The vacuum tester processes and analyzes the ion flow signals in a running state; a signal output terminal of the vacuum tester is connected with an LPZN intelligent on-line monitor apparatus through RS485 network cable connection; a signal output terminal of the LPZN intelligent on-line monitor apparatus is connected with a latching electromagnet and an acousto-optic alarming apparatus. The failure locking alarming apparatus for a vacuum circuit breaker detect vacuum degree of three phases of A,B and C of the circuit breaker and transmits the detected related parameters to the LPZN intelligent on-line monitor apparatus which provides an emergency locking signal after processing information, so that the circuit breaker cannot perform opening operations. In the meantime, the failure locking alarming apparatus for the vacuum circuit breaker produces acousto-optic alarming information and transmits the information to a monitor room of a substation to prevent incidents.

Description

A kind of vacuum circuit-breaker inefficacy locking prior-warning device
Technical field
The utility model relates generally to the vacuum switch field, relates in particular to a kind of vacuum circuit-breaker inefficacy locking prior-warning device.
Background technology
Vacuum switch nearly 20 years in China's extensive use has occupied the very big market space with good cost performance.But also there are many defectives.The critical piece of vacuum switch--vacuum interrupter, in use the variation of gas pressure intensity has determined switch performances in its pipe.If during vacuum interrupter internal gas pressure 〉=1 * 10-1Pa, vacuum interrupter can't play the effect of arc extinguishing and insulation.Under this situation, if vacuum switch on-load separating brake, then easy disruptive conduction causes vacuum switch to burn, and causes transmission line to have a power failure, and causes serious economy loss.How real-time inspection, the operating vacuum interrupter internal gas pressure situation of observation, and prevent separating brake, in time report to the police, be problem to be solved in the utility model.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, provide a kind of vacuum switch under normal operating condition, detect the vacuum degree of vacuum interrupter in real time, when the vacuum arc control device when vacuum degree is reduced to related request, a kind of urgent locking device is provided, prevents breaker open operation, and require when vacuum degree is lower than correlation, send warning message timely, to avoid the generation of accident.
The utility model is achieved through the following technical solutions:
A kind of vacuum circuit-breaker inefficacy locking prior-warning device, it is characterized in that: include vacuum pressure sensor, described vacuum pressure sensor places the vacuum interrupter of vacuum switch, vacuum pressure sensor is converted to ion stream signal with vacuum-pressure signal in the vacuum interrupter pipe and inserts the signal input part of vacuum detection instrument, vacuum detection instrument is handled the stream of the ion under the running status that captures signal, analyze, the signal output part of vacuum detection instrument is connected with LPZN intelligent online monitoring device by the RS485 network circuit, and the control signal output of LPZN intelligent online monitoring device is connected with latching electromagnet, acoustic-optic alarm.
Described a kind of vacuum circuit-breaker inefficacy locking prior-warning device is characterized in that: what described vacuum detection instrument adopted is the online vacuum detection instrument of ZXC type.
Described a kind of vacuum circuit-breaker inefficacy locking prior-warning device, it is characterized in that: described LPZN intelligent online monitoring device includes touch-screen, shows in real time on the touch-screen that the vacuum degree of the indoor A of vacuum extinction, B, C three-phase detects data.
The utility model has the advantages that:
The utility model is by the online vacuum detection instrument of ZXC type, detect the vacuum degree of circuit breaker A, B, C three-phase, and detected relevant parameter is transferred to LPZN intelligent online monitoring device, by information processing, urgent block signal is provided, makes circuit breaker can't carry out sub-switching operation, send sound and light alarm information simultaneously, be transferred to electric substation's Control Room, to avoid the generation of accident.
Description of drawings
Fig. 1 is structural representation block diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of vacuum circuit-breaker inefficacy locking prior-warning device, include vacuum pressure sensor 1, vacuum pressure sensor 1 places the vacuum interrupter of vacuum switch, vacuum pressure sensor 1 is converted to ion stream signal with vacuum-pressure signal in the vacuum interrupter pipe and inserts the signal input part of vacuum detection instrument 2, vacuum detection instrument 2 is handled the stream of the ion under the running status that captures signal, analyze, the signal output part of vacuum detection instrument 2 is connected with LPZN intelligent online monitoring device 3 by the RS485 network circuit, and the control signal output of LPZN intelligent online monitoring device 3 is connected with latching electromagnet 4, acoustic-optic alarm 5.
What vacuum detection instrument 2 adopted is the online vacuum detection instrument of ZXC type.
LPZN intelligent online monitoring 3 devices include touch-screen, show in real time on the touch-screen that the vacuum degree of the indoor A of vacuum extinction, B, C three-phase detects data.
LPZN intelligent online monitoring device 3 provides a pair of often opens (closing) contact, when detecting vacuum level of vacuum arc-quenching chamber decline or leaking into to a certain degree, sends warning message, and starts latching electromagnet 4 simultaneously, prevents breaker open operation, to reach safeguard measure.
