Abstract
The invention relates to an intelligent monitor of a switch cabinet, which comprises a CPU (central processing unit) connected with a power supply module; the intelligent monitor of the switch cabinet also comprises an analog quantity signal input, a switching value input circuit, a switching value output, a temperature measurement circuit, an FS6 gas pressure and concentration measurement and breaker contact travel measuring device and a spring energy storage circuit in respective connection with the CPU; and the CPU also is respectively connected with a liquid crystal display and an upper system. The intelligent monitor has the following beneficial effects: since the only one CPU is integrated with the related hardware and software, so that the installation is convenient, the debugging is simple, the failure rate is low, the maintenance workload is low, the manufacturing and spot debugging costs can be greatly reduced and the operating and maintenance costs can be reduced.
Description
Technical field
The present invention relates to a kind of switch cubicle watch-dog, relate in particular to the circuit module of this switch cubicle watch-dog.
Background technology
Middle and high compressing switch of the prior art often disposed following supervising device cashier's office in a shop:
1, circuit breaker simulates display unit: be used to show be installed in the middle and high circuit breaker branch in the cabinet of compressing switch, close state, isolation switch branch, close state and ground connection disconnecting link branch, close state.
2, whether electrification in high voltage display instrument: being used to monitor the switch cubicle high-pressure side has.
3, circuit-breaker status monitor: be used to detect the following parameter of circuit breaker that is installed in the switch cubicle: contact of breaker stroke, FS6 gas pressure, FS6 concentration, spring energy-storage state, temperature etc.
4, intelligence instrument: be used for the current/voltage of sense switch cabinet, electric weight such as active power, reactive power, frequency, power factor, active electrical degree, idle electric degree.
But because above supervising device is independent respectively, therefore it is complicated to use the switch cubicle annex to install, supervising device is done things in his own way, resource can not be shared, and the indignant rate height that 4 kinds of different scope of offical dutys' supervising device fault takes place, be unfavorable for on-the-spot Installation and Debugging and operation, its maintenance workload is big, the cost height, particularly being connected with upper location supervisory (SCADA) needs 4 road communicating circuits, and 4 kinds of supervising devices often have different communication modes and communication protocol, have increased the weight of the communication work load and the communication system cost of upper location supervisory greatly.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of intelligent switch cubicle watch-dog, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: the CPU that links to each other with power module; Also comprise: the input of simulation volume signal, switching value input circuit, switching value output, temperature measurement circuit, FS6 gas pressure and measurement of concetration that links to each other respectively with CPU and contact of breaker stroke, spring energy-storage circuit; Described CPU also links to each other with upper system with LCD respectively.
Compared with prior art, the invention has the beneficial effects as follows: because it is integrated only to reach relevant hardware and software with a CPU, event is easy for installation, debugging is easy, failure rate is low, maintenance workload is little, greatly reduce manufacturing and field adjustable cost, has also reduced operation expense.
Description of drawings
Fig. 1 is a module map of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: the CPU that links to each other with power module; Also comprise: the input of simulation volume signal, switching value input circuit, switching value output, temperature measurement circuit, FS6 gas pressure and measurement of concetration that links to each other respectively with CPU and contact of breaker stroke, spring energy-storage circuit; Described CPU also links to each other with upper system with LCD respectively.
Characteristics of the present invention are that the detection that separates with prior art has been combined in together by a CPU, multiple functional, combine all functions of " circuit breaker simulates display unit ", " electrification in high voltage display instrument ", " circuit-breaker status monitor " and switch cubicle supervising devices such as " intelligence instruments ".
Function of the present invention has:
1) whether monitoring switch cubicle high-pressure side has;
2) the middle and high circuit breaker branch in the cabinet of compressing switch of monitoring, close state, isolation switch branch, close state and ground connection disconnecting link branch, close state;
3) detect the following parameter of circuit breaker that is installed in the switch cubicle: contact of breaker stroke, FS6 gas pressure, FS6 concentration, spring energy-storage state, temperature etc.;
4) electric weight such as the three-phase current of sense switch cabinet, three-phase voltage, active power, reactive power, frequency, power factor, active electrical degree, idle electric degree, residual voltage, zero-sequence current;
5) manually/the telemechanical switching;
6) manually divide/close circuit breaker.
The present invention can the more timely and correct abnormal conditions of judging and handling switch cubicle with intellectual analysis software with the signal comprehensive analysis in same CPU that collects.The trend prediction function is arranged: can forecast the running status variation tendency of switch cubicle, in time handle in order to the operations staff.
Whether whether the present invention can continue normally to move and report to the police in conjunction with other relevant information prediction switch cubicles according to temperature rate of change.
The present invention can judge whether circuit breaker leaks according to SF6 gas pressure and change in concentration situation and in conjunction with out of Memory.
The present invention can realize " five is anti-" middle requirement: prevent the on-load branch, close isolating switch; Misdelivery when preventing ground connection disconnecting link ground connection; Prevent functions such as charged splice grafting ground disconnecting link.
By the present invention following event recording function can be arranged:
1. can carry out real time record and time thereof following parameters is out-of-limit
A) temperature is got over the upper limit and out-of-limit involution
B) the SF6 pressure upper limit and lower limit and out-of-limit involution more more
C) SF6 concentration is got over lower limit and out-of-limit involution thereof
D) electric weight is out-of-limit: electric current is got over the upper limit and out-of-limit involution thereof
Voltage is the upper limit and lower limit and out-of-limit involution thereof more more
There is power to get over the upper limit and out-of-limit involution thereof
2. can carry out real-time event to following switching value change and write down timely interocclusal record (SOE)
A) breaker closing
B) circuit breaker trip
C) isolating switch closes a floodgate
D) isolating switch separating brake
E) the ground connection disconnecting link closes a floodgate
F) ground connection disconnecting link separating brake
G) telemechanical divides circuit breaker
H) telemechanical closes circuit breaker
I) manually divide circuit breaker
J) manually close circuit breaker
K) alarm signal output
L) alarm signal involution
M) communicating interrupt
N) communication recovers
The present invention only connects, and communication interface of needs (is redundancy requirement with upper location supervisory (SCADA), can make 2-3 communication interface) and a kind of communication protocol, can upwards transfer to the SCADA system to the amount that former 4 kinds of watch-dogs are gathered with a communication interface, reduce communication cost and the connection and the maintenance that have made things convenient for communication.
