Background technology
At present, along with the quickening of power network development speed, unattended substation is widelyd popularize in power supply enterprise, and there are not charged precious metals such as ground wire, managing security tools and instruments, ground connection copper mesh transformer station inside, and the antitheft problem of transformer station is just extremely important.The robber utilizes to cut off entanglement evening, slips into transformer station even cable duct is committed theft, and the operations staff makes an inspection tour and is difficult to find.The enclosure wall circumference of existing transformer station is equipped with infrared warning device, and infrared facility correlation on the wall is installed, and when there is object the centre when blocking infrared ray, device can send warning.But infrared warning device is very easy to receive external interference, has bird to fly between infrared or falls into foreign matter even weather fog when bigger, all can send warning.Therefore whether, can not correctly discern really has the robber to slip into, and infrared warning device very easily destroyed, and a side-cutting pliers just can be cut off, destroy, and it can not be had an effect.So infrared warning device can not prevent effectively that the robber from slipping into transformer station and causing stolen.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides a kind of transformer station automatic alarm anti-theft device.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of transformer station automatic alarm anti-theft device; It comprises the first micro computer time switch, the second micro computer time switch, alarm, signal lamp, switch and the power supply that is arranged in the control box; And be installed in several microswitches on door, window and the outside cable ditch earthing cable of managing security tools and instruments chamber, station master's room; After connecting through lead successively, the first wiring contact of several microswitches of the first micro computer time switch, parallel connection, signal lamp, alarm, the second micro computer time switch, switch connects power supply; The second wiring contact, one end of switch is connected with power supply, and the other end is connected with alarm.
Described transformer station automatic alarm anti-theft device; The door of its managing security tools and instruments chamber, several microswitch parallel connections on the window are connected with first signal lamp again; The door of station master's room, several microswitch parallel connections on the window are connected with the secondary signal pilot lamp again; The microswitch parallel connection of installing on the outside cable ditch earthing cable is connected with the 3rd signal lamp, is connected between the first micro computer time switch and the alarm after three above-mentioned loop parallel connections.
Described transformer station automatic alarm anti-theft device, the first wiring contact of its switch is parallelly connected with a button.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This transformer station's automatic alarm anti-theft device; It is through installing microswitch on door, window and the outside cable ditch earthing cable of managing security tools and instruments chamber, station master's room; When the robber opened door, window or mobile earthing cable, the alarm on the panel of control box can send chimes of doom, can light with the corresponding respectively signal lamp of managing security tools and instruments chamber, station master's room or outside cable ditch; Remind operating personnel to have the robber to slip into, can be good at playing the antitheft effect; And the warning accuracy rate can not cause the situation of wrong report up to 100%, and wide popularization and application in transformer station suits.
Description of drawings
Fig. 1 is the electrical schematic diagram of the utility model.
Embodiment
Through the accompanying drawing example technical scheme of the utility model is done further explain below.
As shown in Figure 1; This transformer station's automatic alarm anti-theft device; It comprises the first micro computer time switch SK1, the second micro computer time switch SK2, alarm HR, signal lamp, switch SA and the power supply that is arranged in the control box; And the door, the microswitch SP1 on the window, SP2, the SP3 that are installed in the managing security tools and instruments chamber; Be installed in door, the microswitch SP4 of window, SP5, the SP6 of station master's room, be installed in microswitch SP7 and the microswitch SP8 on the outside cable ditch earthing cable of 110KV battery limits on the outside cable ditch earthing cable of 220KV battery limits; Microswitch SP1, SP2, SP3 parallel connection are connected with the first signal lamp HD1 again; Microswitch SP4, SP5, SP6 parallel connection are connected with secondary signal pilot lamp HD2 again; Microswitch SP7 connects with the 3rd signal lamp HD3; Microswitch SP8 connects with the 4th signal lamp HD4; Four above-mentioned series circuits compose in parallel a parallel circuit, connect power supply after 1.-2. connect through lead successively the first wiring contact of the first micro computer time switch SK1, above-mentioned parallel circuit, alarm, the second micro computer time switch SK2, switch SA, and 3. the second wiring contact of switch SA is connected on the power supply N line; 4. the second wiring contact of switch SA is connected with alarm, and button SB is 1.-2. parallelly connected with the first wiring contact of switch.
The principle of work of the utility model transformer station automatic alarm anti-theft device: during test, switch SA is in trystate, and its second wiring contact is 3.-4. closed; 1.-2. the first wiring contact is broken off, and presses the button SB, the circuit energising; If alarm HR sends chimes of doom; The proof alarm is in good condition, if alarm HR does not send chimes of doom or chimes of doom is unusual, proves that alarm is out of order.
During normal the operation, switch SA is in the input state, and its first wiring contact is 1.-2. closed; 3.-4. the second wiring contact is broken off, and the first micro computer time switch SK1 closing of contact in the time of setting slips into door, the window that transformer station opens managing security tools and instruments chamber or station master's room as the robber; Or during mobile earthing cable; Corresponding microswitch closure makes the circuit energising on door, window or the earthing cable, and the signal lamp that is attached thereto is lighted, and alarm sends chimes of doom; Can make the staff of transformer station recognize that situation appears in which zone, can stop the robber to get into managing security tools and instruments chamber, station master's room and mobile earthing cable effectively.
With an embodiment work of transformer station's automatic alarm anti-theft device is described below.Slip into a fan that transformer station opens the managing security tools and instruments chamber during window as the robber; The microswitch SP2 that installs on this window is closed; The first signal lamp HD1 lights, and alarm HR sends chimes of doom, can make the staff of transformer station know that the someone attempts to get into the managing security tools and instruments chamber by lighting of the first signal lamp HD1; Can effectively stop, the warning accuracy rate is high.
