Abstract
The embodiment of the invention provides a simple electricity testing device for a 35-kilovolt handcart switching circuit. The simple electricity testing device comprises a handcart switch rear cabinet door, an electricity testing door, a lock, a converter, a locking mechanism and a locking plate, wherein the locking mechanism and the electricity testing door are arranged on the handcart switch rear cabinet door, the lock is arranged on the electricity testing door, the locking plate is interlocked with the locking mechanism, the converter is connected with the locking mechanism, a locking pin of the locking mechanism is inserted into the locking plate when the converter shifts so that the locking plate cannot be released from the locking mechanism, and the locking pin of the locking mechanism is separated from the locking plate when the converter restores so that the locking plate can be released from the locking mechanism.
Description
Technical field
The invention belongs to power technology field, relate in particular to a kind of 35KV handcart switch circuit Simple electricity testing device.
Background technology
In the operation of electric power system, guarantee that power transformation safe and reliable operation is primary and one of most important requirement.A fairly large number of processing ease generation misoperation in power transformation operation, the incidence of increase accident.In order to reduce or avoid the generation of misoperation, must compress power transformation operation staff's operational ton.
At the operational ton that guarantees to reduce under equipment safety operation personnel, need to first improve reliability and the reasonability of power equipment.At present in the maintenance electrical verification process of indoor the complete sets of equipment 35KV bus and circuit, need first wheelbarrow switch to be released outside cabinet by test position, again electricity-testing handcart is advanced in cabinet, then electricity-testing handcart is shaken to service position by test position, carry out again electrical verification, so greatly increase operations staff's operation, extended the operating time.Therefore be badly in need of a kind of easy electroscopic device to guarantee under the safe and reliable prerequisite of powered operation, reduce power transformation operation personnel's operational ton.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of 35KV handcart switch circuit Simple electricity testing device, can guarantee under the safe and reliable prerequisite of powered operation, reduce power transformation operation personnel's operational ton.
For achieving the above object, one embodiment of the present of invention provide a kind of 35KV handcart switch circuit Simple electricity testing device, comprising: wheelbarrow switch rear cabinet door, electrical verification door, lock, converter, blocking mechanism and locking plate;
Described blocking mechanism and electrical verification door are arranged on described wheelbarrow switch rear cabinet door, and described lock is arranged on electrical verification door, described locking plate and blocking mechanism interlocking;
Described converter is connected with blocking mechanism, and during described converter displacement, the lockweight in blocking mechanism inserts in locking plate, and locking plate and blocking mechanism cannot be threaded off; During described converter reset, the lockweight in blocking mechanism departs from from locking plate, and locking plate and blocking mechanism can be threaded off.
Preferably, when wheelbarrow switch is in test position, described converter reset.
Preferably, when electrical verification door close lock and wheelbarrow switch in when operation, described converter displacement.
35KV handcart switch circuit Simple electricity testing device in the embodiment of the present invention is not only simple in structure, easy and simple to handle, and dependable performance, can reduce power transformation operation personnel's operation, guarantees to reach in powered operation the requirement of safe and reliable power supply.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic perspective view of 35KV handcart switch circuit Simple electricity testing device provided by the invention;
Fig. 2 is the front view of the 35KV handcart switch circuit Simple electricity testing device in Fig. 1;
Fig. 3 is that the installation between locking plate, lock and blocking mechanism is related to schematic diagram.
Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 shows the schematic perspective view of 35KV handcart switch circuit Simple electricity testing device provided by the invention, and Fig. 2 is the schematic perspective view of this 35KV handcart switch circuit Simple electricity testing device.Please be simultaneously referring to Fig. 1 and Fig. 2, the 35KV handcart switch circuit Simple electricity testing device in the present invention comprises wheelbarrow switch rear cabinet door 1, electrical verification door 2, lock 3, blocking mechanism 4, converter 5 and locking plate 6.
Wherein, blocking mechanism 4 and electrical verification door 2 are arranged on wheelbarrow switch rear cabinet door 1.Lock 3 is arranged on electrical verification door 2.Locking plate 6 and blocking mechanism 4 interlockings.
When converter 5 resets, the lockweight 41 in blocking mechanism 4 departs from from locking plate 6, and locking plate 6 can be threaded off with blocking mechanism 4, so just can open electrical verification door 2 and carry out electrical verification, realizes electroscope function.
Below describe the use procedure of the 35KV handcart switch circuit Simple electricity testing device in the present invention in detail.
After electrical verification door 2 is closed and locked, wheelbarrow switch is also in operation, converter 5 displacements, and the lockweight of blocking mechanism 4 will be inserted in locking plate 6, and locking plate 6 and blocking mechanism 4 cannot be threaded off, and cannot open electrical verification door.
When needs carry out electrical verification, as long as when wheelbarrow switch is moved to test position, converter can reset, now locking plate 6 can be threaded off with blocking mechanism 4, and operations staff can open electrical verification door and carry out electrical verification, realizes electroscope function.In whole process, reduced operations staff's operational ton.
As can be seen here, 35KV handcart switch circuit Simple electricity testing device provided by the invention is simple in structure, easy to operate, and dependable performance, can reduce power transformation operation personnel's operation, guarantees to reach in powered operation security reliability requirement.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
