Description
Technical Field
The invention belongs to the field of transformer substation safety equipment, and particularly relates to explosion-proof equipment of a storage battery chamber.
Background
At present, in order to ensure safety in a storage battery chamber of a transformer substation, fireworks and switchings are generally required to be forbidden indoors and the installation of switches is forbidden; and due to the particularity of the battery power supply, it is also required in regulations concerning batteries: the positive pole and the negative pole of the storage battery cable should not share one cable, the cable is suitable to adopt an independent channel and is laid along the shortest path, the positive pole and the negative pole of the battery outlet are not allowed to share one cable, and each cable should adopt a single-core flame-retardant power cable.
The existing electric energy transmission mode is to directly transmit electric energy through two cables, and a protection device is arranged at the tail end of the cable, but the protection device cannot protect the cable. Since the switch cannot be installed at the battery outlet, only the end equipment can be protected, which can cause the cable between the battery chamber and the direct current screen to be unprotected. When a short circuit occurs in a cable, the failure cannot be removed, and the short circuit between the battery electrodes is directly caused, which may cause a fire due to burning of the cable or explosion of the battery. Therefore, to ensure safety, a dc protection should be provided at the battery outlet. However, most of storage batteries in the transformer substation are lead-acid valve-regulated storage batteries, flammable and explosive gases such as hydrogen, oxygen or corrosive gas sulfuric acid vapor can be generated when the storage batteries are used, if a protection device trips, even a tiny spark can ignite the gas or ignite the gas, and serious safety accidents such as fire disasters can be caused.
In order to avoid the above accidents, the conventional practice adopted at present is: the storage battery chamber is not provided with any protection, and electric energy is respectively transmitted outwards through two single-core cables. But the disadvantages of this are: once the double-circuit cable for transmitting electric energy is subjected to interphase short circuit, fire, storage battery explosion or other unpredictable results can be caused, and the method is really a great hidden danger for safe production of a transformer substation.
